What and where was the worst service you've ever received in a restaurant? How bad was it?

1961 in Virginia. I was traveling with a black friend and we walked into a restaurant after driving many hours over night. Was about nine AM. Two guys came out from behind the counter and told my friend to get the hell out of there place. I sure started to learn about the South in a big hurry that day. I know things are different now but this was before all the civil rights upheaval later in the 60s. We left for sure and from that time on we would buy food at a market and fix it ourselves . We could not find a place to stay any place in the south that both of us could be in the same room and most places would not even let blacks stay there at all. My black friend was going to university at the time and was at the top of his cl and later got his degree in political science and then went ahead and got another PHD in business Psy.. He now is working for the UN and very well off. I have been to the south since then and was treated well but I didn't go with a black at my side. I don't have very good feelings for the white attitude in the south even today. No I am not black.
