I am afraid we have no dined at the same resturants, or had the same experiences. I have not found a signifcant decrease in the quality of service between the $50 per person returant and the $6 per person resturant, except perhaps the atmosphere. And that is not a function of the waiter's service. I found this to be true in the several different states of a variety of cusines at a variety of price points. I believe the server is being tipped for things that are not a function of their performance.
Here's why, I asked several people I know if the tip changes in any of these circumstances
1. Climate of Resturant (too hot, too cold)
2. The timing of the food
3. The quality of tea, soft drinks, mixed drinks
4. The quality of the food
5. The ambience of the resturant
6. Time until being seated.
I asked all the people to list 10 things that influence the tip. 76% of them included at least one item, upon further examination, was not a function of the sever's performance, but of the resturant's performance. Therefore, you are over-tipping if you base your tip on the RESTURANT's perfomance over the SEVER's performance. In which case one can over - or under-tip unfairly. If you are going to tip, you should have metrics which grade the individual's server's performance.
Here is a short list of things that do influence the tip, and are based on the server's performance
1. Did the waiter remember it or write it down. Extra tip for memorizing
2. Did the waiter hand the person the food they ordered, or did the discussion go "Beef Tips?", "Oh, that's John's"
3. Attire of the sever
4. Attitude of the server
5. Did the server chew gum
6. Was the server attentive to one's needs
7. Knowlegde of daily specials
8. Knowledge of the catch of the day...(even though most people don't order it. I don't understand why it matters, but it does)
Needless to say, you will probably say (like my professor) that I need more observations. But he does agree that the majority of customers who tip "on service" (by their own admission) do not accuratley grade the server's performance.
- Does the preparer at Burger King mess up the order or does the counter person record it incorrectly?
And I have never needed help with a menu. I dunno, it's just me I guess.
