All of a sudden you realise that you're acting like her man-bitch, holding her fucking purse.
Thankfully there is a quick way to get that dignity back, assuming that you think fast. Just open her purse and start rummaging through it. If she asks what the hell you're doing, say: "I'm looking for your condoms, I'm out." She'll never give you her purse again.
Compliance tests are such a bitch to deal with, because they're usually done so naturally - and you've had umpteen years of conditioning to make you reflexively submit. So rummage through her purse, or sip her drink, or whatever.
Not perfect yet, always striving to improve.
