Praise and appreciation is nice, yet, these two men sound like they are crossing the line, by asking about your bf history and frankly, complimenting breasts in the workplace, it is way out of line.

"I appreciate the compliment and interest, however, there is a time and a place. This is neither the time nor the place."

As far, as your doing anything different. I am not sure this is anything different that you've been doing. These men, are just crossing the line. They are your clients, not men outside of the workplace. And, how would it feel to have a man, standing in line at Starbucks, turn and say, wow, you have really nice looking breasts?
