Back in the 90's, I used live and work near the Pepper Canister, I used to love to walk the canal even when I didn't have the price of a punt on me.
Some girls were very popular, might show up, see 2 to 3 clients an hour and they were gone within 2 hours. Other girls hung around for hours, barely seeing a client. Had a lot to do with level of service, as prices were generally the same and very little to do with looks, as some of the most popular girls were ugly as the come.
My wife caught me wearing ladies underwear and threatened to leave me.
So I packed up all her clothes
And left.
