My son's manager - Unreasonable?

[gabsdot45]

My son has been working as a delivery driver for a local fast food place as a second job.
Last weekend he said to another driver something like
"I don't like the food here, it's very overpriced and I wouldn't buy it"
He was overheard, without him knowing by the manager.

Next day she texted him to say that she was very upset by what he had said. He apologised but then she cancelled his next shift and has not rostered him this weekend. So it looks like he has lost the job.

Personally I think the manager is being ridiculous but I'm interested to here what other people think.

So YABU - The manager is right to be upset
YANBU - The manager is being ridiculous.

It is a lesson for your son. I am sure for the vast majority of people, we are sadly not personally invested in what we work in. We are literally there to earn money. But those remarks don’t go well when you’re an employee. I think it is a valuable lesson in the world of work

Exactly.
And it's basic professionalism.
A concept seemingly lost on both the OP and the son.

Bloody hell. Why not go find a maternity ward and tell a new mum her tiny baby looks like a baboons arse while you are at it.

While this is ridiculously extreme, it did make me laugh 😆

We need to think of more possible job faux pas in the same vein. What about telling a client in a hair salon not to waste their time and money when a paper bag will two eyeholes would be free?
