I found out my gf would change in front of her co workers [cuckold]

My gf worked at McDonalds for a brief period through college as it was easy and the hours were good. She got super close with a bunch of the guy workers there which I didn’t love at first but soon came to enjoy it. They would always drive her home and offer her to come hangout and what not which she did. Anyways fast forward a few years and I became friends with one of the guys that worked there. One night of drinking and going out it got brought up some how which is when I learned that apparently she used to just straight up change in the break room or whatever it was. He was saying how she didn’t even care who was in there and would just strip and change before her shift. These were the same guys that I hated at one point since they would always try to sleepy with her. Since I’m into this whole thing now I was incredibly turned on when I heard that and immediately tried to dig for more info. He said that’s pretty much all she did but would always sit in guys cars after her shift was done.
