When dining out, a 20 percent tip is usually considered standard. So imagine one restaurant staff's reaction when a customer left a staggering 500 percent tip.
As WBBM-TV's Dana Kozlov found out, the tipper didn't leave anyone out after dining at Boka restaurant in Chicago's Lincoln Park on Sunday night.
Server Brandon Anderson says a customer named Mike dined with five friends before heading off to a concert. Before leaving, Mike thanked Anderson for his service and meal and then asked to thank the kitchen staff.
Mike spoke with the 17 kitchen members and then gave them each a $100 bill.
"We were all speechless," said Anderson.
Then, he left Anderson a $200 tip on his $400 dollar tab.
"He definitely came across as extremely genuine," said sous chef Richard Graham. "It came from the heart. It didn't seem like a stunt or some rich snob or anything like that."
Staffers say they don't know anything about Mike except he's from Seattle and this was his first time in Chicago.
