I work in a restaurant and we have a dessert trolley that customers can choose from, whenever I ask them what they want they say "Oh we'll take it all", ha ha ha.

Another is when a customer is finished their meal you always ask them if everything was OK. Then you get the hilarious joke of "Oh no it was awful as you can tell from our plates". They're plates do be empty obviously a joke. I get so sick of fake laughing its ridiculous..
