He has a guitar shop, it's not a big jump to fetish equipment from there, probably some of the same customers.
And I concur with Prosebass, one of the petshops in my home town has closed recently, the reason is that the owners of the building put up the rent so the business become unprofitable.
Now all that's there is an empty shop, that strikes me as stupid on the owners part, as instead of having rent at X, they wanted rent at X + Y, but instead they've now got 0 coming in from it and will still be paying some basic outlay on the building.
Some people are just too greedy.
