Are you really worried about it? Seriously tell the people who have a stick up their asses to go fuck themselves-this is nothing to post a question about. What about the Burton Love series, the entire Hook-Ups skate company line (and that is what I could think of off the top of my head) you will have like one person make a problem out of it for every twenty that even notice it (and they're BINDINGS nobody will notice). Go watch the GNAR movie **spoiler alert** nobody had a problem with the peoples shenanigans except the managers. All the lifties, customers, etc., all thought it was hilarious and a good time.
I agree with besercka your biggest issue is that you're representing Grenade, which means the gear might break on you any second.
