This. 1 of my boxing trainers was using Venmo since 2016, and he even asked me to pay him through that at that time. So I came home and did some research, and in that process, found some payments that my other trainee friends had made to him, on his facebook wall.

I was like WTF?! Why would anyone broadcast their financial transactions, that too for something like Personal Training.

Moreover, the transactions I saw, for the exact same type of training I was receiving (pad work followed by sparring for 1 hour), was 20% to 40% less than what I was paying, and I felt like I was a sucker. I stopped training with him a few weeks later.

Never used Venmo either.
