in my previous working life, I was verbally threatened on more than one occasion as a Dixons store Manager . I came awfully close once to decking some loud mouth two hat who said he was going to knock me out. One of my colleagues grabbed my arm to restrain me but, there comes a time when enough is enough. Thankfully, I saw the errors of my ways and calmed down while someone else escorted him from the store.
I find it so concerning to see people working in stores, verbally abused/assaulted, and next to nothing being done to the scum that causes them grief.
