If you are doing something with someone, regardless of what it is and it makes you uncomfortable and you do not communicate with that person after being asked, if it was alright several times it is not their fault that you feel uncomfortable. they did their job asking you if it was OK and you told them yes.
For context the other day we had a new cashier come to the floor for the very first time and I was their coach for about an hour and a half till their new coach came over and took over for me after I came back. I was on a different register. I had come across something that the new trainee had not yet been showed, and I asked his coach and him if it was all right that I showed him how to do this, because he had not been told how to do it yet. So I showed him. it was hex, nuts and bolts that we had to figure out how to identify. I thought he was doing a really good job, and afterwards I sent him back to his coach.
Come to find out that he and one of our assistant managers made a complaint about me the other day, because I apparently made him uncomfortable, pulling him away from his coach. After I had already asked him and the coach, if it was all right (multiple times) that I showed him how to do this thing. I get that he’s new I was probably shy, but he was a grown ass adult and should be able to tell other people when he’s uncomfortable.
