I'd rather rinse but I've eaten off un-rinsed dishes lots of times with no bad side effects. SalfordUSA made a good point about the logistical difficulties of trying to rinse without a double sink (something I always had back when I was learning to wash dishes as a kid in the US). In answer to the question, we have a dishwasher here so it's only pans, knives, and the occasional thermos that get washed by hand. I wash them, drain the water, and then rinse under a running tap.
