I always try to get to Starbucks before school starts. This is the reason. Once they dump the older kids off at the local school, a whole bunch of mums (I've never seen a dad) pop into Starbucks for a coffee. Most of them have a second (or third) child with them and they take over the place. Naturally there's not enough room to park inside and this is what happens. It's like a sign saying "No Room For Normal Customers At Present" at the door. Works for me.
