My boss has always touched my shoulders, will grab my hand and hold it for a brief moment, kisses on the cheek, and at times a hand around the waist when he stands next to me. He has also made comments that were mixed signaled, where I thought he was coming on to me but I wasn't 100% sure. When he touches me or comes on to me I'll try to find an excuse to walk away. He never does anything around anyone else. Recently he had a bottle of expensive scotch that he insisted we drink at work with another employee, when she left the room he implied that we should stay and have more fun after she leaves, and then he tried to kiss me even though I said no. He also asked me I could get pot because he gets horny when he's high and he wants to smoke it with me even though I told him I don't smoke.
