Bill Gates might be worth nearly US$100 billion, but all that money can鈥檛 buy him the ability to cut in line.

A viral photo posted to Facebook shows the Microsoft co-founder standing in line at Dick鈥檚 Drive-In, a fast-food restaurant in the Seattle area.

Mike Galos posted to Facebook Jan. 15, saying in a reply to a comment that the photo had been taken by an acquaintance who used to work for Microsoft.

He also said he had previously spotted Gates at a different fast-food joint and multiple Thai restaurants.

鈥淏ill鈥檚 not big on attention but is generally friendly and understands he鈥檚 a bit of a celebrity,鈥 he wrote.

The photo had been shared more than 18,000 times as of Monday morning.
