Unexpected supplemental services

I went to a massage parlor the other day. After a very nice massage and a HJ happy ending, the masseuse offered to cut my toe nails. Having my toes nails cut is not erotic to me (but I'm not judging those who might get off on it), but it is a nice service, especially as our bodies age and become less flexible. I've also had hair stylists offer massages and "anything else I can do for you." But I haven't pursued anything erotic with a stylist. It got me to wondering what other unexpected services, erotic or not, others have encountered.
