Happens a lot to most women. Granted, this one sounds more polite than most, usually the invitation is somewhat more graphic.
Once took a computer service call at the UAW headquarters in Detroit. Was located about 1/2 mile up river from downtown at the time. One thing I noticed was that everyone in the building had a major attitude problem. Here I was trying to help them and they looked at me like I was their enemy. They had no idea what my politics was, but still gave me the attitude. Was glad to leave the place.
