Snow is here!

We usually don't get snow over where I live, and when we do, it's usually not a whole lot. This winter however, seems to be different.
I live in an apartment block, above an apothecary. There are 6 parking spaces in front of the building. The four in front of the shop are for customers, the leftover two are for the people in the building. There are five of us. Once in a while we park in front of the shop, and it's really no trouble, as long as we leave enough space.
Now snow is here, and the lady in charge of the shop shoveled the 4 spaces for the customers, and naturally didn't do our end.
So here's my question: who should? Personally I wouldn't mind going down there and clean them up, but I really don't feel like doing that work and finding out another neighbor took the spot. I realize I have no claim on the spot, we all have a garage at the back (but with this snow and no shoveling it's not quite easy to get there without damage), the two spots are just there to make things easier. Now that I have a baby to haul around, I find those two spots very handy

Legally it is stated that the owner of the ground floor apartment should shovel. But he's old, and he never parks there.
I'm halfway tempted to shovel the spots, hang up a paper on the door stating I did so, and suggesting we might take turns if the snow keeps up like this. DH however foresees that nobody will pitch in, and that our upstairs neighbors will happily park BOTH of their cars in the two freshly shoveled spots
Any thoughts?
I could always leave it as is for now, the snow isn't that bad that you can't park there.
