Yes. People ask for mine all the time. A lot of people may not even keep them but if someone asks it’s always better to have one than explain why you don’t.
Even if the practicality is taken out of them, there is still a use as a business formality.
I don’t. I know every industry is different but I deal in a few and business has overall trended downward for most people.
That being said I know Costco has been doing record numbers so big money is still being spent at places.
