Customer's who question the calculation of the till. Resulting in me having to show them with a calculator that their purchase equaled what the till said because they didn't believe it. Even though i printed off a docket with all the items listed and prices T_T. Stupid luddites. This gets annoying during Christmas time when some purchases are $100-$300 in smallish gifts, revolving around $10-40 each. Only happened to me twice but i got really pissed off.
Also customers who do not read the fine print. Clothes sale, 40% off all Children's/Men's/Womens clothing, then underneath it says "Excludes underwear, socks, lingerie and hoisery" in medium font which isn't exactly hidden from view. And then the customers get shitty at me saying its false advertising blah blah, blame me even though me, the simple cashier doesn't make the advertising produced by the chain stores, they never really think about it do they T_T. And then you have to remain calm the whole way through while they yell and verbally abuse you. Don't you just love christmas time, a time of Christmas cheer, jolly good times and carols?
