Not a good morning

This morning for breakfast (Marriott Courtyard).  I walk into the room, wait staff are all there, no one comes up to me to get me a seat or even tells me to grab an open table.  I grab a table.  At courtyards, its a buffet breakfast and they bring you coffee.  Not for me!  After getting some food, I finally go find some coffee for myself.  After I finish they DO come take my plate, but do not bring the bill...  They are by no means busy.

After about 20 min I get up and ask for my bill at the checkout.  

No tip for you!
