H-E-B review: Unethical behavior of cashier and manager

The week of July 22nd I went to the smaller HEB in San Marcos with my daughter who is about to attend Texas State in the fall. We were standing in line when the cashier, Monica, starts talking to what I'm guessing is her manager some girl in a different colored shirt about smoking weed together. They went on and on about how they haven't smoke with each other in a while and need to get together and how she could get a fake id so they could go out together. I heard their whole conversation, its like they weren't even scared of getting caught but why should they be when one of them is a manager. I am about to drop my daughter off in a whole new city to attend school and it just made me greatly uncomfortable to hear about drug usage and see that these girls weren't scared of any repercussions. I thought HEB was a drug free store! I don't want my daughter exposed to this. It still is not legal in Texas and I don't want my child to think its no big deal when people still get arrested and thrown in jail for this. I just thought it was completely unethical to be speaking about these things out in the open at work especially with a manager. There are plenty of other kids out there looking for jobs who won't just stand there talking about smoking weed but actually work. These two should be reprimanded and looked into. This was not a manager relationship but rather one of two gossiping high schoolers.
