Last week, Sandler went into the I-HOP in Manhassett but left when hostess Dayanna Rodas, 17, told him there was a 30-minute wait.
"He had a mask obviously, it's hard to recognize people," Rodas told FOX 5 News. "Also, he had a beard. I have never seen Adam Sandler with a beard so I was like I don’t think it's him."

Sandler got wind of the video and responded on Twitter: "For the record, I only left the IHOP because the nice woman told me the all-you-can-eat deal didn’t apply to the milkshakes."
IHOP wants to make it up to the Sandler with a freebie inspired by him.
‘All You Can Drink Milkshake Monday’ will be in effect on May 10 from Noon to 8 p.m. at all 19 locations.
For every milkshake sold nationwide on Monday, I-HOP will also donate one dollar, up to $50,000, to Comedy Gives Back. The organization helps comedians who lost income during the COVID shutdown.
