There's a sign at my local McDonald's stating that the drive-up window is for motorized vehicles only, eliminating not only bicyclists, but horse-drawn carts as well.

Haha, That's funny. But Clients are clients, from the city or from the village.

In the Old Order Mennonite area of southwestern Ontario, around Kitchener-Waterloo, supermarkets have hitching posts for the horse-drawn buggies.
