Lmao you got cooked! Congrats you experiencing what sales and entrepreneurship is. Don't worry about those comments, only take them as lessons for you to improve, at the end they just a number, a lead that you came across to reach out, shared a little bit of words and that's all, next. Now try to improve your pitch, I suggest doing split test between your openers. And above all, do what that guy told you. Be authentic and honest. As business owners they have been reached out too many times that they tired. Also I recommend you to figure out what kind of owners would be more open to hear YOU, not your offer. Because trust is based on people and their thoughts, and it's better to have an advantage on that. In my case I'm into home improvement and I try to reach to owners that speak Spanish (since I'm latino lol) so I can get their attention faster and make some jokes and try to connect them as a real person. That's all. Hope you can improve and just keep grinding bud!
