I'm a little self conscious , but it's getting easier. Vaped first time in a Mexican restaurant on Sunday. I did ask the waiter if it was ok first and then my wife and I just vaped away. Sitting in the car waiting in a parking lot at trader Joe's an older couple got in their car in front of me and watched me for a while before leaving. The husband ran over a curb by mistake , so perhaps flustered a bit at what he had seen (or new vehicle, or just a bad driver).
Outside I have no issues at all....stores I feel a bit weird.
