"In NYC, especially in the East Village, there's a massive concentration of incredible bars, and all of the bartenders working are close friends. The trouble is, we all work and are too busy to see each other. So... if we had a cool guest who was heading to one of our friend's bars after ours, we would make a little cocktail and wrap it up to go with a message, and put an inflated plastic glove on top of the glass.
The glove would be tied into a permanent middle finger, and the guest would carry the shot, message, and f*ck you glove to the next bar for the bartenders. Eventually, they would send one back our way, completing the ‘Boomerang’. During my last shift at Amor y Amargo, I received 12 Boomerangs, two pizzas, and an order of fries from bartender friends who were stuck at work and couldn't make it to the bar." – Chris Lowder, Bar Manager at The NoMad Hotel
