I had a new customer in today, I work in a vape shop. He was after an ecig, so I went through the usual questions, including having any lung complains, he answered no. However I noticed that he has clubbed fingernails, which usually indicates a lung/heart problem, in particular lung cancer.
He is away now and I keep thinking, should I have said something? It's not really my business or my job and I don't know whether he would be upset with me. I just keep thinking I should have said something.
He will be back again I am sure, so WIBU to mention the nail clubbing to him next time? Or should I just mind my own?
