Was this girl just flirting with my bf in front of me?

This is just a curious question I have. I’m not angry about it but I was just thinking if she was flirting, then that’s pretty dispresctful and I hate people like that.

So, here’s the story. My boyfriend and I went to a fast-food restaurant. He ordered and then realized he made a mistake on our orders. He told the girl, “I made a mistake I meant to order a small strawberry shake.” and I told the girl, “And I want a small oreo shake.” She looked directly at my bf instead of me and said, “I’ll have that taken care for you okay?” with a smile and eye contact. I thought she was just being nice.

Then she gave him a free sundae. I was thinking, “Oh she’s nice.” and then I realized he got a BIG strawberry shake when he ordered a small…and I didn’t get an upgrade. I also notice he didn’t get charged for his shake and got a discount on his meal. O.o I didn’t get free anything, upgrade, or a discount.

My bf happened to be wearing his workout shirt that shows off more skin after we got off the gym. He seemed to attract more attention this way. I never had this happen to me before lol..Usually I’m the one that gets attention but in a rude way from stupid men.
