So today I was opening GSA and about 2 hours into my shift my store's HR team member signed a new TM up for a redcard. I then jokingly said to her something along the lines of, "I don't think I should call this one out, it's kind of cheating getting a team member to sign up." I then proceeded to recognize her over the walkie RIGHT IN FRONT OF HER. I didn't think anything of it (just a harmless little remark) but then a few hours later the LOD came to me and said that she wanted to "follow up with me about what happened earlier" and the the HRTM was offended by what I said. I've been at my store for two years and what I said was definitely something that anyone would say. I'm worried that now I'm on the bad side of HR and I really respect this particular SrTL and I'm worried that she lost some respect for me today. I already apoligized to the HRTM in person but I'm still worried and it's kind of ruining my day. Any advice on what I should do?
