Upper East Siders (Yorkvillians?) are upset about 7-Eleven opening up on their block:

Residents of one Upper East Side block worry their peaceful existence is about to drown in the icy waters of the Slurpee.

The convenience-store chain 7-Eleven is opening an outlet Nov. 7 at the corner of East 84th Street and York Avenue.

And some neighbors are predicting nothing less than catastrophe.

A flier posted yesterday on the Web site curbed.com foretells the demise of the neighborhood via “rowdiness, serious beer drinkers, taxis on breaks and other undesirable” elements.

The 24-hour store will cause litter, attract rats, and attract drunks looking for beer, neighbors worry.

“I’ve never had a Slurpee, but I can see those Slurpee containers in the street,” fumed Judith Cutler, who lives on York Avenue. “I’m concerned about the transients . . . [in] the neighborhood.”

People, my god! We’re not talking about a Wal-Mart here! And who among us has not sampled Slurpee? Shame on you . . .
