When I started punting in Soho, I used to go to one girl, have a pint and something to eat, then see another girl. Now I find it more satisfying to have one longer punt with one of the good models (e.g. Selina, Roxy, Kate, etc) and walk away feeling happy about it.
Last week I was going to have 2 punts. Saw Ruby in Romilly Street for 30 mins and really liked her service. Went out with a smile and didn't feel like doing the 2nd punt after all.
