I agree with everyone who sez to go hang out in the store a bit first. You couldn't pay me enough to have to deal with the cornballs who think Harleys are number one. These people are the special ed kids of the motorcycle community. They live a lifestyle based on total fantasy, pay double the money for the worst bike made outside of China.
It could be an easy gig, selling accessories to people just dieing to pay ridiculous prices and who walk in totally sold on the quality of anything with Harley written on it.
If you do take the job, study up on the Harley history and lore and parrot the party line about Harley being all American and all about pride and tradition. And I hope you don't mind being around a bunch of retards, posers and geriatric old fogies.
