The only attention I've had is the usual one of people being interested in the fact I still use a film camera. It's always positive or neutral but two weeks ago I was shooting an event with a Canon T90 (easily mistaken for a DSLR at first sight) and a chap with a Nikon D-something just kept glaring at it as though I was personally holding back technological progress. Perhaps he thought I shouldn't be breathing the same air as someone who'd blown £3k on kit.
Some people need others to follow in order to feel validated. You may have made him too aware of how much he spent.
