One of the worst experiences in dog grooming? When a customer neglects to pick up their dog. This is happening to my boss right now. Her husband had to go to his second job, leaving my boss and her young son at the shop until 1:00 am. All because someone left their dog at the shop. The lady probably won't even tip her!
Oh, yeah, another thing--always tip your groomer unless they do a terrible job! If you tip your hairdresser, you should also tip your groomer. Groomers don't get into this business for the money. It doesn't pay well, and it can be gruelling, thankless work. So put a little sunshine in the day of someone who loves your dog almost as much as you do!
