I work hard to remember to get rid of the one dollar bills. Left those in the pants a couple of times, and I had some splaining to do come laundry day.
Disposing of extra condoms and the wrappers is critical. I don't think there's an explanation for that.
Hand stamps are a particular irritation that reflect badly on management in my opinion. Why would a club want to mark its customers bodies with evidence of their attendance? I have not gotten those completely washed off before, and also had some splaining to do that time as well.
Getting rid of odors and glitter is also critical since my SO is very observant and has a bloodhound's sense of smell. A change of clothes and shower usually takes care of that, although occasionally she can pick up some residual odor even after that. When the shower is not possible, I have recently started applying very small amounts of the body wash that I regularly use. This seems to work really well. It masks the girls odors and makes me smell like I had a shower.
I also regularly delete GPS history, although that might be overkill.
In other words, I do all the usual stuff that the other PLs do that also have a SO.
