This kind of person often meets when shopping. Those people are simply hooligans. You'd better ignore them when you meet them. That little gift was supposed to be given to you, but it turned out that you were going to try it out with him, and then you had to buy something from him. Scold you if you didn't buy it, even threatened you, which made you lose the good mood of shopping. So don't be too kind to help those who hand out leaflets and give gifts in the future. You were kind enough to help them reduce their orders, but you were cheated.
