The newly opened Hakata tempura is really bad in terms of sanitation. The cups have tea stains and the small dishes have vegetable residues.
The waiter now said, "The cup will get smudged after it is used."
I said, "But this dirt will come off when I pick it up with my nails."
Just give me a new cup~
Isn t cleanliness a basic requirement for catering?
