Barnes & Noble Booksellers

I am a regular customer at the barnes & noble bookstore in the lansing (mi.) mall. On two occasions an employee has cautioned me about wearing a mask. I believe the first time was in december 2020, when I was sitting alone in a chair drinking a latte with my mask in my hand. I was told my a female employee (name unknown) to put my mask on. She saw I was drinking a latte I purchased from barnes & noble (as I do every week), & said "I could put my mask down between sips". Then she sent jason the local manager over to speak with me. He only said it's company policy to inform management when it involves a mask. Then on friday (1/27/21), this same employee tells me again when my latte is beside my mouth about to take a sip. She again says I must put on my mask which I had dangling on one ear, trying to drink the latte as fast as I can for fear of being harassed. I also want to say that in november, 2020 in the starbucks seating area, I witnessed michael (prior manager before jason) socialize with his wife & 2 other people. None of them had masks on! The starbucks employees had to have seen them but no one said anything to them or reported it to management! I do have a witness who saw this as well. I would like this complaint to be forwarded to area supervisor who is over the entire bookstore.
