I don't think there is anything wrong with this as long as they told her up front, I should print this and toss a few while driving down the M5, I am sure there are a few woman there who would prefer this as opposed to standing on the corners.
And personally I would not mind a PA who puts in a little extra you know
Someone mentioned a poor desperate woman, what do you think happens to these poor desperate woman at the end of the day?
Although I would be pretty pissed if this happened to my lady so I sympathies with OP. Id want to beat some heads in.
