I was with my husband at a baseball game in Boston’s Fenway Park when I decided to go get myself a hot dog. As I stood up my husband asked me to buy him a beer. The young clerk at the concession stand asked to see verification of age.
"You’ve got to be kidding," I said. "I’m almost 40 years old." He apologized, but said he had to insist. When I showed him my license, the clerk served me the beer. "That will be $4.25."
I gave him $5 and told him to keep the change. "The tip’s for carding me," I said.
He put the change in the tip cup. "Thanks," he said. "Works every time."
