i am sorry for your lame experience with what was probably a great analog photo store ( or is that analogue ) ...
i have never been to henry's, only talked to the staff on the phone when a once popular photo equipment mail order
company went belly up and henry's surprisingly acquired all their "stuff" it was mostly lame backdrops it seems.
anyways sorry again for your problems. when i usually speak to phone sales staff who are clueless
i ask for a "supervisor" or "manager on duty" and if they are completely clueless i never call them again.
the last time this happened was after i contacted toyo about a recessed lensboard ... they said it was "dealer only"
and the nearest dealer i knew after they told me the name .. after i telephoned, and the staff had no idea what toyo was
and i asked for the manager, and HE had no idea and didn't even know they were a dealer, i gave up.
kind of funny though the recessed lensboard was hugely overpriced where i bought it, and it would have cost at lest 1.5-2x that amount
if the "dealer" had a clue and didn't blow the order.
nothing like someone clueless on the line ... i feel for you ...
