I really hate the system of tipping (as in paying someone twice for a service). This isn't because I'm mean, but because I find the whole thing cringily embarrassing. Whom to tip, and now much? On the rare occasions when I use a London taxi, I tend to over-tip wildly in my efforts to keep the driver happy (one of my sons was thrown out of a US taxi because he had apparently not given a big enough tip).
You ask for a service, you get it, you're charged, you pay. Fine. Then you pay a bit more. Why? I don't get tipped, and I doubt whether you do, either. I'm sure the whole thing was set up so that employers could pay their staff as little as possible, but wouldn't most of us prefer to pay a bit more for services, and not be expected to tip as well? At least we'd all know where we stood.
Yesterday, fourteen of us had lunch at a certain well known pizza place. I never add the tip to the credit card payment as I KNOW it doesn't go to the right person. I gave our lovely waiter a nice tip, and he kissed me on both cheeks.
Maybe there's something to be said for tipping after all....
