I shower at work after the ride in.
Sometimes I go for a run at lunch time, and need a rinse off after that. In those occasions, the towel wasn't drying out in time. I got a speedo sport towel, which is a microfibre cloth that is magic. Squeeze it and it becomes DRY. It is the size of a facecloth, but will dry your entire body. It feels weird sliding across your skin, though. Like a sham-wow! lol.
