In the UK there's no similar pressure by companies to give tips, and it's still very much up to the individual whether they tip or not.
Jenny and I usually give tips to cabbies, restaurant staff, hairdressers, housekeeping staff in hotels, and sometimes to coffee shop staff. We don't refuse to give a tip unless we've had very bad service or a very bad experience of some kind.
We know that most of the people we give tips to are likely to be financially stretched and probably rely on tips to make ends meet. They may very well be getting no more than the legal minimum wage for working in tough conditions for long hours.
Of course they should be earning a decent wage that lets them be free of money worries, but the reality is that they're not getting a decent wage and probably never will be.
An interesting tip situation arose on our recent trip to Edinburgh. The hotel had a policy of not servicing rooms unless the guest asked for it, presumably to reduce the number of staff needed and reduce the amount of laundry.
That was fine by us, except that we only had our room serviced once so that leaving a tip for that one day seemed excessive and we didn't leave one. Unfortunately if other guests thought the same then the housekeeping staff's income from tips must have been drastically reduced. Did the hotel raise their wages accordingly to compensate? Somehow I doubt it.
