i worked in a supermarket cafe for 4 years, and got moved to night shift a little under 2 year ago. the cafe experience was very similar to that of regular retail, but with added bonuses
1 - strict on piercings, not due to fashion, but because bits might fall out. i totally understand this, except my piercings can only be taken out with pliers... i had to wear bright blue tape over my ears, despite the fact that i had to wear a hairnet
2 - customers got angry if a food item/meal was out of stock. the usual complaint being 'but you're a supermarket, why don't you go and get it?!'... yes, because we totally hand prepare every meal from scratch, have the time to do that for every person who asks for it, have enough staff to deal with you, have enough staff to send off department to go shopping just to make your meal, and are allowed to do it in the first place. the cafe was owned by the supermarket, but a completely different department, we were completely separate from the rest of the store and had our own product delivery.
2.5 - customers get angry for a lot of other reasons too. in the cafe we had a thing called the '**** club', which was exclusive for certain members of staff who had been called a **** by a customer. some of the members incidents were:
a) a customer came 10 minutes after we had stopped taking food orders. he argued that he saw food orders going out and therefore he should be able to have one, not seeing that the food has to be cooked before it can be sent out, and if we operated on his ideals we would never get to shut down and clean the kitchen...
b) a customer could not get a meal he wanted, because the person before him got the last one. said member of staff refused to serve him, and he complained to the store manager, who agreed it was unfair... that he didn't get the food he wanted. the store manager demanded we specially prepare it for the customer and take it out of the next days stock, and the customer got it for free.
c) a customer complained she didn't like an ingredient in her sandwich after taking a bite, not realising its contents. the member of staff allowed her to swap for an alternative free of charge, happy to help. said customers' husband comes back, accuses the member of staff (who was gay, incidentally) of trying to chat up his wife, and called him a ****. as the member of staff walked away, the husband took a swing at the member of staff, but missed.
d) i was inducted because i asked to see a customers receipt after they claimed they had been waiting for a food order for some time, and i needed proof of their purchase before i could sort anything out. they refused, got really angry... turns out they didn't have a receipt for the £80 food shop and £300 TV they had in their trolley either, as security came to investigate
3 - there were often clear signs saying 'wait time for food is currently x minutes', when it was above 20. customers still complained because they added in the time they waited in the queue, which if only 1 person was taking orders AND making all the drinks meant the queue time was pretty long too.
4 - near the end of my time working there (and one of the reasons i left) they introduced a new policy, i had to wear a snood because i wasn't clean shaven. at that point i had a very short beard (like, could be called long stubble length), and they claimed it would fall into food. thats fine, but they made me wear it when i wasn't even near the fucking food. after a few weeks of customers calling me hannibal lecter, i refused to wear it and went home, after arguing with my dept manager and two store managers on the basis that customers were taking the piss, and i had worked there for over three years without a single complaint about ANY of the staffs facial hair. i moved off department the following week, never looked back
