smile, talk slowly, respect him, have fun, make sure he's comfortable, don't rush, show him around the place at first, offer water quickly, ask if he has questions......you may need to direct him if he's not stripping fast enough ("do you need to take your shirt off to cool down a bit?"....."it might be more comfortable if you take off your pants to reach that high shelf"......"gee, you've been working hard....would a full body massage feel good right about now?").....
I suppose you're not really going to be worrying too much about how good a cleaning job he does??!!
and make sure he gets "down under" the tables for a thorough cleaning......
