I've been taking my dogs to get groomed at the same place for years. The first time I went years ago, I tried to tip the guy who did the grooming and he said he doesn't accept tips. Incidentally, he is the owner. Yesterday, I bought my dog to get groomed and the lady who was at the front desk who I handed the payment to looked like she was expecting a tip. Now I feel terrible because I came with just the amount for the service. What is the proper etiquette here? Does the owner not expect a tip but everyone else is supposed to be tipped? I never really know who the groomer will be working on my dog. Am I supposed to ask who the groomer was and hand them the tip myself?
