Here are some examples:
“The staff member suggested I go to [competitor] because they are a little cheaper”
“The store was closed at lunchtime although the trading hours say they should be open”
“The staff member didn’t give me a receipt and seemed to put the cash in a different drawer to the cash register”
“The staff members were talking amongst themselves and ignored me despite my eye contact. I walked up to ask for help and they simply pointed to the shelf I was already looking at”
Find the truth and, then decide what to do with it. Otherwise you will fix imaginary problems and ignore the real ones.
Don’t believe that you know the truth. Reality is rarely what you believe. Rarely.
