I tip 15-25 percent depends where I eat and what type of services they give me. One time I was so disgusted with this restaurant, the waiter had the balls to run out telling me I was short on my tip after the service they gave me and my lady. We waited for our food for like 2 hrs. I snatched the tip and put it right back in my pocket and keep walking with my lady. Any experiences you had in the past with giving tips for services?
