I've been on the receiving end of bad haircut (just two months ago!), no tip there. But I was talking with someone a few days ago, and they said they give $5, no matter what. I say, they are professionals, do a good job, talk with me if I feel like talking, stay mostly quiet if I am, and don't yank my hair out, and you get your $2.
I used to do pizza delivery, so $2-$2.50 if they are prompt and come as promised. $1 if they are more than 5 minutes late, and I've stiffed once or twice if they just didn't seem to care. It's funny, I used to give 50 cents or a dollar at most before I worked for Domino's.
Restaurants: that's a whole other ball of wax. I give 15% for great service, 20% for amazing service and if service/management went out of their way to make darn sure I return and tell friends. On the other hand, I've given 10% if they don't refill drinks and slap down plates, and worse if they just don't give a darn (when you have to beg for orders, food, drinks, bill).
As much as I loved getting the odd tip for taking groceries out to my car, I prefer to take the groceries out to my car myself. If there's a ton of food, then good help is nice...and I'll give a dollar. But just as we weren't allowed to take tips then, usually I play "tempting devil" and offer one just the same. Rarely do they accept it though.
I don't frequent bars much, but I usually give about 10% over the bill. I prefer to drink with a meal or at a private establishment/friend's house
I've only been in a taxi twice and the amount was around 10-15% both times. I've never needed a bell-hop, it was just an example.
Well, I've never given anyone at a coffee shop a tip...it's their job and I know their pay isn't a tip wage. But I was just curious if I'm a mean old coot for not doing so! Now when I went to Spain, my dad told me the standard for food service was around 5-8%, or the 100 peseta coin in your pocket (around $3.30US) for a sandwich.
Well, after going to the Picasso museum, I went to the cafe for a drink, (café con leche) at a counter. I walked up to the counter and seated myself. The fellow who served me the drink walked about 2-3 paces to serve it to me. I gave him the amount in total (about 100 pesetas, or 60 cents) and received the muttered phrase "****ing American" in return.
I don't understand, I'd bought drinks before at a counter in that country, that was the first time I'd been given anything other than a thank you or a smile. I'm sorry, there was no extra work involved, therefore, no tip. (Everywhere else I went in Spain was a wonderful expereince, by the way; never any hostility towards being an American visitor.)
Well, that's my experience. I suppose there were many times I cursed not getting anything when driving to poor areas of Gainesville, pizza in hand...
