I can't help but think that the low end bike (and perhaps his attire) isn't consistent with the image they want to project. I recall one time as a young man getting kicked off a golf course because I had ratty clubs - well, only two clubs (I didn't want to overburden my caddie), and the mesh t-shirt and cutoffs detracted from the decorum of the course. I think. Threats of police, confrontation and shouting, a generally bad scene; I wouldn't wish that on OP. Maybe it's better to let sleeping dogs lie. Or if I may be so bold as to make a suggestion, OP could hire a photographer to compose a glamour shot with the bike out on the road, too glamourous and exciting for the shop to resist.
