yeah Colin you'r right....In most cases it's usually the "Working man" who tips the most.
In saying that, I done large domestic a job for 2 barristers recently (5 br,hsl,lr ad 2 rugs). No tip when job was completed but then 2 days later got a call from them saying their dog had an accident on one of their freshly cleaned rugs and could I come by and clean it again for them.
Now the rug was only a cheap polyprop, small and very easy to clean so I when I was in the area I called with them, cleaned it and wasnt going to charge them. He (the customer) was having none of it and insisted I take £20.00. Thing is the rug was only worth £35.99.
