“They all said, ‘Listen, we were there, having a good time, and we want to pay our tab,’” said Tony Castagnozzi, owner of the Rattlesnake Bar, who said he has received a flood of calls since the April 15 terror attack. “I was speechless. … You see there are so many good people out there. It makes you feel good.”

Castagnozzi, who has owned the Boylston Street bar for 23 years, said his customers were forced to leave behind more than $3,000 in unpaid tabs when cops evacuated them after the bombings. Since then, he’s received nearly a dozen letters and calls from customers who’ve made good on their bills. In all, Castagnozzi estimates the bar has recouped about $1,200.

The first call came from a man from Denver who had a $91 tab and called to give his credit card over the phone. Then came calls from Florida, Virginia, Rhode 
Island, New Hampshire and across Massachusetts.
