Retired former pound-for-pound king Floyd Mayweather Jr. has once again criticized the behavior and antics of close friend Adrien Broner.

Mayweather, now a full-time promoter, has one of his fighters - Ashley Theophane - challenging Broner for the WBA junior welterweight title on April 1 at the DC Armory in Washington, DC.

Broner's recent video that was posted to the internet showed the boxer inside of a Wallmart, where he threw money all over the floor after getting his change - sarcastically telling the cashier that he's too rich to accept any change.

Mayweather believes these types of antics are only hurting Broner's career. The former five division champion has tried to mentor Broner over the years, but his advice is falling on deaf ears.

"I think fighters hurt themselves sometimes. Someone showed me the clip of Adrien Broner the other day. He was in Walmart and what was so crazy about the video when I looked at it, it kind of hurt my feelings. The person gave him his change back, I guess he had bought something and he threw the money or the change up in the air like, "Why are you giving me change back? You don't know who I am?" Actually, a lot of people in the store didn't know who he was. They was looking like, "Who are you?," stated Mayweather to Fighthype.com.

"And then, it's so crazy, if you're at such a high status and you reached a certain level, you're supposed to have people going to Walmart for you. You go to places like Walmart to save money. Of course you got to realize this, he's still young and he's still learning, but before you know it, it's going to be too late. I mean, I didn't really understand it. At the end of the day, he's hurting himself; he's not helping himself. He has a lot to learn. He has a lot to learn."

Mayweather feels Broner's behaviour has affected his progression as a fighter. Although Broner has captured four world titles in four weight divisions, the opponents were not of the same caliber as those that were beaten by Mayweather.

"By the time I was his age, I was a much bigger star. I fought a lot better competition than he's fought, you know; not knocking him, you know, because he only can fight who they put in front of him. I mean, his two biggest fights were against Shawn Porter and Maidana, right, and he came up short. I think he won a world title like, what they say, 3 or 4 times. I know he won one against Paulie Malignaggi, but I don't know who else he won a title from," Mayweather said.
