next to the fruit & veg stall in our local market 
We were both stood there, looking at the apples so right up against the fruit. He turned his head, phlemed up and spat it out, then turned back and carried on.
I said "I'm sorry but that is just disgusting, at least use a tissue and move away from the food if you are going to be so vile."
His wife shot me daggers and made comments to him about me being a rude bitch. Now ok the gentleman was older, probably about 60 and may have been ill (I'm trying to find a reason why he may have felt this was acceptable) but REALLY? Even if you have a condition/cold virus/bronchitis or whatever, you carry a tissue and dont spit on the street next to food? WIBU? They were totally unapologetic.
