I don't get tipping. First of all, if your shop includes some routine checks and adjustment as part of the service, I'm of the belief that they are not going to go out of business because you don't give them free money. It was figured into that original charge and in many cases is trivial for them to accomplish costwise.


Secondly, don't tip and make up for it at the dollar store and dollar menu. That is not logical at all. Pay everyone fairly...or to be blunt, don't be a cheapskate.


Tipping has to be figured in as income and taxed, so you are not doing anybody a favor.


However, I can see you are generous in your mind and mean well, still, the notion that you are being good to somebody by paying them extra in some way is not working. If they wanted it, they would tell you up front. That doesn't mean that stuff is free, it just means they don't mind.


I always let the owner air my tires for me as I am liable for damage to the tube etc and not under any warranty if I mess it up. He does let me wrench a little, simple things, if I am out of the way as he's busy. What I don't know or don't want to do is his job or I wait and figure it out later/


I get looks and comments about what a slug I must be not to tip, but like a previous poster I give my money again to those that earned my praise and thanks, and come back. The business owner hopes you will come back and needs you to return more than $2. Some customs are well-meaning but not practical.
