Underwater Tourist

A quick example:
Most of my recreational diving was done in peripheral EU + places like Egypt where I could always ask for nitrox and nobody ever cared nor asked if I had a nitrox card.
When I started diving in NA and SA, even fully tourist oriented dive shops wanted to see a nitrox card.
So if we extend my example from recreational to technical world:
How likely is that I will be asked to show something like "advanced nitrox" card if I go to a tech shop and ask for a 100% O2 bottle?
