Because I have found some clients like me to wear perfume, I ask them when they confirm their booking - with regulars I have a good idea who likes or is ok with perfume, and who isn't. Quite a few new clients are surprised I ask, the 'going home smelling of' is not something that concerns them or even occurs to them.
IME women have a much better sense of smell than blokes
Good stuff that you give them a heads up

, hopefully the penny will drop
Heading home with a smell of 'eau de fanny batter' unlikely to work out well
Especially with an inquisitive OH who is in full on investigation mode suspecting that hubby is getting action elsewhere
