I have only taken Ella to the groomer once so far. I plan to take her next week for her last full grooming until next spring. When i took her for her first grooming i was so pleased the lady added in the tip without telling me until i looked at the reciept. I wasn't really upset because Ella looked beautiful, but she could have told me. Point is, tip them if they did what you asked, don't tip if they didn't.
