Last week in the absence of person C in my office, person A asked me to instigate production of roller assemblies for 2 different customer machines (machine 1234 and 5678).
I completed the tasks 100%
Today person A walked into the office and asked person C if there was production raised for the roller assemblies I dealt with last week, referring to the customer name ABC rather than either of the machine numbers originally stated.
I asked person A, "Do you mean the ones you asked me to raise for machine 1234 and 5678?"
Person A ignored me and carried on talking to person C (who knew nothing about the transactions, or their current status)
I took this as being ignorant, and left person A and person C to look into it, left the office to do another task, and smugly realised they were still looking into 20 minutes later when I returned to the office.
I left work 10 minutes later and they were still looking into it.....
You can't help some people.
