You had breath mints and you still didn't offer him any??? Goodness, does one have to explain the nuances of subtle suggestion??

My dance bag is packed with a few things, shoes, fan and shoe brush of course, and packets and packets of chewing gum and mints. At the most opportune (or inopportune, depending on how one looks at it) moment, I open a pack of chewing gum and politely offer it. The alert ones get the hint and accept my generous offer. The less than alert ones, well, dance with me less frequently for the rest of the evening. And of course, they bear the red asterisk next to them for future dance endeavors as well..
Of course, the next best thing to do is to practise to hold your breath for 2-3 minutes while dancing aerobically - and live to tell about it of course.. 
Shame we can't offer deodrants though...
