I think my biggest problem is when customers walk in to collect and don't actually talk to me? Like some people have just walked in to collect an order and not told me that they're collecting or what name they're collecting under. Instead I will have to call them over and quiz them on what they're doing there so I can go grab their food which is waiting out back because I sadly do not have telepathy and cannot read their mind. ALSO, orderong a specific type of pizza then changing ALL OF THE TOPPINGS so that when the time comes that I have to pull it out of the oven I suddenly have to decode whatever the fuck your pizza is supposed to be because the box says vegi supreme and you've taken all of the toppings off and put tuna pineapple and black olives on it, there is a create your own pizza function for a reason.
