You were correct first time.
Both of my visits I've agreed the rate and services,pulled out the notes and she's said "anything for my maid?" From the Soho thread I gather £2,is perfectly acceptable but some give more. Don't want to start the meet asking for change from a fiver.
Last week I had a full set if appointment s booked with my clients with Shaftesbury. Ave booked for 2pm. Next one booked for 4.30. Perfect and the £2 in my pocket felt sweet. Then every one kept offering extra work and I ran right over. Normally that would be a great day but I'm still really missed off.
Other half better leave that £2 sitting on my side of addressing table.
