I really didn't know what to say. What do you say in a circumstance like that if you feel uncomfortable? I had already given the voucher to the flight attendant, so it was no longer my property. If this is a standard practice, I guess I just need to "suck it up". Flying over 100 Southwest flights/year, I have never seen this happen before. If the general consensus is that it is no big deal, I will drop it. If others think it is as uncomfortable as I do, I will likely write a letter to Southwest asking them if there is another way to handle this.
