The chip-on-his-shoulder Long Island bagel shop customer whose viral rant about dating turned into a brawl is going back for another bite, he told The Post on Thursday. “They just invited me over for a free bagel,” claims Chris Morgan, a 45-year-old Bay Shore cleaning business owner. Morgan said his phone has rung nonstop after he was caught on camera Wednesday morning at the local Bagel Boss location, where he was lashing out over being repeatedly rejected by women because of his 5-foot stature. “My phone is blowing up like the president,” Morgan told The Post. “I haven’t even got to my friends.” And Morgan says the rant seen ’round the world has suddenly changed his luck with the ladies. “I got girls hitting on me I don’t even know,” he said.
