Not sure if it's my profession (accountant), but both my current and prior workplaces have quite a number of frugal colleagues (even more than half of the partners) so it becomes quite difficult to organise eating out at more expensive places, yet my spouse, who works in the CBD in law, would have colleagues just casually go out at lunch time and buy expensive bags or shoes.
What's your workplace like?
It depends. Teachers are frugally stealling each others lunch, staffroom cutlery and complaining about the lack of free tea and coffee.
On the other hand, they grossly overspend on unnecessary cr@p for their classrooms from Kmart. 🤷♀️
