I work at an ice cream shop at a campground for city people so I hear some pretty stupid shit which at first I think they may just be jokes, but I fear that they are probably serious questions...
1)
Customer: "Are you guys open?"
Me: "No, we're just sitting here in work shirts, with doors open, lights on, and people playing air hockey & pool"
2)
Customer: "You serve ice cream hear right?"
Me: "Sir, you're standing in front of our ice cream display case which is right in front of our soft serve machine which is right next to our cone display. AND you just saw me scoop and serve an ice cream!"
Best non-work one for me though is my 17 year old friend who is not game-savvy at all got a brand new xbox 360 elite and called me a few hours after he told me he was setting it up saying that it wasn't working at all and wanted me to drive 20 minutes to his house to look at it. I did and when I got there I took one look at it and said, "Dude, you don't have it plugged in..." he responds with, "Oh, it has to be plugged in?"
