the good with the bad

I've been at my current job for coming on a year and I've seen a lot of waitress come and go. There have been some good and bad ones,   which isn't unheard of. I get along really well with my coworkers and chill outside of work with a lot of them. For me it's key to have a good time with the people you work with. But there's this one waitress that's special. When she started working she was very nice and pleasant to work with and after 10/12 weeks she no longer has the easy going vibe. Nowadays the only time she talks to me is when there's vomit or broken glass to clean up.
