Amazingly, not computer related
I work on the deli in my local sainsburys when im at home from uni, earning my beer money sort of thing.
Standard practise at a deli, you take a number, when its your turn, the big red lcd screen overhead beeps pretty loud and moves to the next number, and the number is shouted out by the person ready to serve somone.

too often, one of the following happens:

1) you shout the persons number to their face, and they dont respond, staring back, despite repetition. so you shout the next number, which usually wakes them up and makes them go crazy with waving and shouting.
Sometimes they're down an aisle and come sprinting from across the store with ticket over their heads.
2) some think they still need a ticket when theres no other customers at the deli and there are 5 colleagues doing nothing, looking at them, asking if they want help, even chasing after them as they slowly walk towards the ticket dispenser, asking repeatedly what they want.
3) people wait for 20 minutes in a huge queue to get some olives, which are on the end of the deli and are self service , with signs saying so.
4) People who know only how much cheese they want in terms of size, but try to convert that into an approximation of weight (usually in pounds and ounces which the scales dont do, we have to whip out the conversion chart), which we then have to guess in terms of size when we cut the damn bit of cheese.
5) people who just walk away when they have ordered everything they want. no thanks, not even a "thats everything", sometimes they're just putting things in their trolley, so you have stand there in front of 10s of people waiting to be served watching them to see if they're coming back.

Doesnt sound too bad, but with probably 70% of customers doing one or more of these you do start to despise the general public.
