Pffft beats me. I'm not sure if I've ever done an epic fail of epic proportions.
I'll get back to you on that one, if I can think of any.
Edit: Got one! My most embarrassing and stupid moment ever, by a long shot.
See what I share with you people? You should be grateful
Right, I was with my mates in a supermarket grabbing a load of junk-food to take to the cinema, and I wasn't paying much attention to anything at all. I think I was 16 at the time. Well, whilst I was putting my stuff through the checkout I noticed this shaggy-dressed woman hovering around watching me.
Well, after half of my crap had gone through the till she waltzes over and starts grabbing my stuff and bundling it into some carrier bags with haste. Now I was highly confused. What was this mad woman doing with my stuff? Why does nobody notice what's going on here?
Well, after she'd grabbed and bagged most of my stuff, I turned to her, grabbed the bag and said (quite loudly): "Excuse me. That's MY stuff."
She looks at me awe and states: "*Ah! *chuckles* I'm just a charity bag packer!" before laughing some more to the hysterics of my friends. I mutter out an apology and walk out of the shop with my head bowed in shame.
I had died a little inside. It was my most stupid moment ever and I generally like to think of myself as not as stupid person. I know these people exist, I've seen them before, yet right at that moment my brain seemed to be away on holiday. She'd jut finished packing the bags of the friend before me and others were stood at the ends of each till up and down the shop doing the same thing. Such an embarrassing story. I'd all but erased it from memory.
