As a customer, I don't get to spend time in the kitchen or check the fridge and dishwasher temperatures. Even if the county health department inspects the place, I want to feel that the food I'm eating was prepared hygenically. If the part of the establishment I can see is clean, I assume the kitchen is as well. The contrary implies the contrary. If the waitstaff appear dirty or unwashed, I presume that the kitchen staff and facilities are similarly unwashed. If I'm not able to wash my hands with hot water, soap, and dry with clean towels in the restroom I presume that the staff hasn't either. And no, I've never mentioned the level of cleanliness to management. I just never return.
