Well, their reasons are slightly different for their cross border rules than ours in Canada. They changed significantly after 9/11 and I can't really blame them for that.
They do come to my door with the imported stuff, almost every time. It's when I order something locally, that I frequently experience the lazy guy drop off at the franchise outlet. To add to my ire, I've often arranged my day around being at home to receive a delivery that never reaches my door. And this is confirmed by my finding an attempted delivery notice down in the lobby of my apartment building. I did call and complain about it at one point which significantly curtailed the lazy guy syndrome for a period.
