Panera Bread review: about the service/workers

i was ordering at Panera Bread and the cashier Davena was being just being annoying and rude. Mid way she kept cutting me off saying "is that all" constantly. Which made me annoyed how she kept trying to rush me while i was still ordering more items. She then started giving off an attitude and left the front. Then once my order was ready the other girl in the front gave it to me and said "have a nice day" making it seem like my order was in complete. But once i got to my car and started driving i noticed that half my order was missing. i had to go back in and get the rest of my order which is something i shouldn't have done in the first place if my order was actually complete. Once i got to my car again i looked at my receipt of items and notice i still was missing a coffee. So i went in again angry how they still forgot to give me my drink. the girl said it was self serve with an attitude like i knew that, which should've been said at the cashier in case people didn't know that cause clearly that can happen. Once i got my coffee cup i saw they didn't even have the coffee i ordered out, a hazelnut flavored coffee. How are they going to let me order something they don't even have out already prepared. I was just so over it and i got my stuff and left quick regretting even picking such an expensive place that provided terrible service from the workers in the front. And to top that, i got home and started eating my sandwich and i went to go reach for the chips i ordered to go with it and it WASN'T even in the bag. Also, i definitely ordered a chocolatechip kitchen sink cookie and she gave me a regular cookie instead. My favorite meals from there and it wasn't even complete. I've been to other panera's and i've never had this constant mistake happen, only at the Panera at Somerset, Nj.
