I think the current consensus, amongst those baristas who think their task here on earth is to edumacate us, is that a ristretto is sexier and perceived to be of higher quality than the plain, old fashioned and very old school simple espresso or short black. I say bullocks to that as I am sure you are old enough to know what kind of coffee you prefer. But... better safe than sorry... so perhaps it might be wise to order an espresso and letting them know you definitely do NOT want a ristretto. Be prepared for the frowns, rolled eyes and general looks of incredulity.
Good luck with that
