I’ve not read through the whole thread but to put the boot on the other foot.
How would you feel if the checkout operator was gassing away on their mobile whilst serving you? If its not acceptable for the shop staff to do it, then it certainly isn’t acceptable for customers to do it.
I’m home/field based and all of my work calls are via mobiles. If I’m busy, meeting with a customer or talking to somebody, I never answer my phone in those situations. However I’m shocked at the number of times other people answer when I ring and then tell me that its not convenient or that they are in a meeting. If its not convenient don’t answer, I’m more than capable of leaving a message!
And yes at 41 years of age, I really can see the Grumpy Old Man syndrome sneaking in! 😉
