So here's a weird thing--the English don't seem to rinse things. I noticed it with dishes when we've visited friends here. There's one sink of water with soap. You wash the dishes in the water and then sort of swish them around in the water and set them on the sideboard to drain. No rinsing. No separate sink of non-soapy water. In fact most kitchens I have seen only have one basin in the kitchen--not two sections of the sink like my sink was in the States.
I haven't seen a traditional carwash here yet either. Instead, in the major grocery stores or at the mall there's a 'handwashing service.' They have a little cart with a bucket of soapy water and rags and sponges and that sort of thing. The cars look plenty clean when they're done. I still can't figure out how they rinse it though! There's no hose. There isn't a separate bucket of clean water to rinse with.
So I'm flabbergasted. No rinsing. Go figure...
