One of my recent tour members said it would be good for me to have a post about having cash for toilets and how much to tip.
If you’re coming to the UK on a plane, the airport bathrooms are free. Toilets at some of the train stations and other public restrooms require coins to use the toilet (that’s what they call it over there – it took me a long time to get used to that). Some require exact coins to be put in a slot. The ones I have seen have all been 10 pence so you would need a 10 pence coin. So before you leave the airport, have some cash and get change in coins if you are going to be out and about.
I believe the taxis in Edinburgh and Glasgow take credit cards. The taxis in Bath were cash only.
Tipping is not a way of life in Ireland and the UK like it is here in the US.
You can give a pound or 2 to taxi cab drivers.
For meals, if you have a server come to your table, you can round up to the nearest pound or leave a pound or 2 extra. 20% is over paying. Their staff is paid a salary and not dependent on tips.
For tours, 5-10 pounds per day per person for the driver/guide is normal. People have tipped Inverness Tours between 20-100 pounds per person for a 6 day tour. (I think 100 is excessive, but the guides from Inverness Tours are fabulous!)
