*Has tea too*
I feel for you Feyth. I actually started having the odd ounce or two of coffee work got so over run. I hae a customer tap me on the back of the head with a product she wanted to ask about while I was trying to see to another customer.
I used to work in fast food with a cheap boss who always tried to get away with as little staff as possible. This did mean that I was once stuck manning front counter, food prep, and drive through at the same time since the other employee was taking her sweet time with her break with the supervisor out of the building, never mind the rules around breaks when there are only two people.
