I think you're all forgetting the hipster market.
If there are enough in a three mile radius and there's a decent roasting/coffee shop who'll let you set up in the corner then you could make it work......
'Guaranteed to clean beard oil from your newly purchased vinyls'
(Note 'vinyls' plural which annoys the eff out of me when the hipster nephew uses it)
Free parking for single speed bikes, 10% discount if you're wearing a plaid shirt, free box of artisan cereal with every 50 vinyls de-oiled...?
