If a client wishes to avail himself of my bathroom facilities he is more than welcome, I have plenty of hot water, towels and soap. Some shower at home, others will ask on the way to the bedroom. I don't mind as long as he is nice and clean for me. A quick shower only takes a couple of minutes, and shouldn't make any difference to an independent. I often will stand and chat whilst holding a towel. I have been known to lend a hand, sometimes chaps prefer a bath for which I have been known to assist with the soap.
