A North Carolina waitress just got the biggest tip of her life: $10,000! Alaina Custer was waitressing at Sup Dogs, a hot dog eatery in Greenville, when two customers came in and ordered glasses of water. That's it. "When I went back over there they were gone and there was a note on the table on a napkin that said, ‘Waters were great,’” Custer told Inside Edition. “Then just the stack of $100s sitting there and I was like, ‘Oh my gosh,’ and I thought it wasn't real."
