Frustrated at work.

Another day, another fifty cents. Just referring to the fact that they don't pay enough to up with the @$%# that I have to at work. Last night my cover left at 1am, as always. Normally this is not a problem, that course depends on who is working in the kitchen. The lady that I worked with last night, the same one that I usually work with, seldom answers when I buzz, hardly ever watches the till so that I can get my sandwich production done and she does she will help until her chicken runs out or the customers are gone, at which point she says 'can I go cook or do whatever she has to do.' Last night for example, she ran till for awhile and then had to go cook. She said she would be right back. When somebody says they'll be right back - I don't expect that to be an hour later. To make a long story short I should've had my prod. done at around 2:30-3:00 instead I was done at 4:30. So now I'm two hours behind, the store is a disaster and I have an hour and half to cash out and clean up the store before the boss comes in. As they say crap rolls down hill and at 7-11, because I work at night, it lands on my head. I get yelled at first about what wasn't done from 4, when the manager leaves until 6:30 when she arrives. I've just about had enough of it (nights at 7-11 or maybe 7-11 period).
