I’ve got two parking spaces behind the shop – it’s two units joined together, so two numbered spaces. I usually use one of them. Is it greedy to want the other one kept clear for my customers?
There are other businesses in the row which only have one space, but have more than one car. There’s also some new housing just built, and there’s some visitor parking spaces.
On the other hand, I presume some portion of my rent is meant to pay for these spaces, and I do get people driving up from a long way away who need to park relatively near the shop for mobility reasons.
So, stop fussing if someone else uses the space? Put a sign on it? Invest in a wheelclamp? (kidding about that last one)
