Oh no... sorry to hear that. I was there on sat, and reached their booth around 7 plus, near to closing time. Most of the sales people looked tired, but nevertheless, were friendly and helpful as there were quite a few customers there. Some customers were obviously first time hobbyist as they were asking rather interesting questions, but the guys there seem to handle them well, so I was surprised that this happened to you. I agree that customer service is one important factor for me to revisit a place again.
