Sam's Club review: Customer service

I used to work at this store on Cypress Creek Pkwy & 1960 and then I got terminated over a year ago. I never stolen anything from them. I shop at the store because it is close to my house. I go in, get what I need, and mind my business. The last time I shopped there was March 20, 2022. I can see one of the team leaders (Delvin) that I used to work with sending a message over to another team leader. I ignore him and continue to shop. I get to self check out and see the whole team in the front of the store and all eyes are on me and my fiance'. How embarrassing?! When I got ready to walk out they scatter like flies! Before I continue to pay for this membership, is this legal?
