I will not pay a mandatory "service fee" even if it is a place I have gone to for years! If the business cannot afford their expenses, they should raise their rates, and I will most likely pay the increased rate. I will not let them try to put their hand in my pocket because of their greed or lack of business acumen. If someone owns or operates a business they should not try to tell their customers to cover their business expenses. After final bargaining for a new car purchase, I tell the dealership "Now deduct the dealership fee or I WILL WALK AWAY. I have gotten out of the door but never was able to leave the lot before it was deducted.
