A good Greek boy would never eat any food unless he had previously been fed it by his mother. Obviously there are exceptions but the rule works far more than it fails.
Again there is/are Indian restaurant(s) on the Platanias tourist strip in summer. I tried one once but I wasn't impressed. All dishes tasted the same.
Typically there are two long green peppers commonly sold in Greece. Τηγανητά are the larger ones and, as the name suggests, are normally fried, either whole or cut into rings. They are not spicy at all. You don't see the slightly smaller καυτερή type often in Crete but they are sold everywhere in northern Greece. There they are grilled or barbecued to blacken the skin and then served warm or cold in olive oil. While they do vary I have eaten them hotter than the small green peppers used in Jalfrezi. Numb lips and a sore throat. My neighbour would always order a dish whenever we ate in a taverna and the hotter they were the better. He wouldn't dream of eating curry because, "It is too spicy". Go figure.
I think it is perfectly possible to make curry the same as Indian restaurants serve in the UK. If people are interested there is a book by Kris Dhillon called The Curry Secret, which is specifically aimed at "How to Cook Real Indian Restaurant Meals at Home", i.e. its sub-title.
