Ten minutes after being seated I asked the bartender to find a server for our table. Another server who was closing out got us drinks and took our order and was never seen again. Food came out after other tables seated after us. Finally our assigned server zipped by and said "oh, good you got your food".
I suppose there are going to be bad days, but at least offer an apology for not serving.
When pay time came, the pay system was prefilled with an 18% tip. Normally that would be fine, but not this night.
