Still working when I'm off...

So the restaurant that I work at I so happen to live like 5 minutes away. My family loves eating there after church for breakfast. Fortunately, I have Sundays off and I like it because I get to spend time with my family. Although sometimes I don't like going where I work to eat because I feel like I'm there so damn much. Also because I feel weird that the waitresses that I work with are serving me and I'm just sitting there enjoying my food. This morning, we had one of the newer waitresses serve us. She's kind of ditzy and sometimes I think she doesn't know what she's doing but anywho. She comes to our table and I'm watching her waiting to see if she'll recognize me while she's putting down our settings. Once she sees me she's like, "Omg, why am I doing this?" "You should be doing this!" I'm thinking okay yeah I can do it but like I should just serve my own table then. So I take the settings and I start setting up my OWN table and then I tell her what drinks everyone wants (because we go there so often that I know what everyone wants). She goes to go get it and I'm like you know what I'll help her out and write out on a piece of paper everyone's orders. So I write down everyone's order and gave her the paper and she's like wow that helps! And then she takes forever to get our drinks and our toast. Then she comes out with the food and she has no idea where it all goes so she's like here I'm just guna give all the food to you since you know where it all goes. After we're done eating I'm gathering all the dirty plates and piling it so that it's less work for the buss boys. Then she takes forever to give us the check and after all that my grandma pays and she gets a 15% percent tip. I mean yeah she was a waitress but I think I helped her out a lot.....JUST SAYING lol.
