A vendor at the Miami Dolphins' stadium was arrested Sunday after charging an unsuspecting fan $724 for two beers, police said.

Nathan Collier, 33, who was selling beer at Hard Rock Stadium in Miami, completed the fan's purchase with a personal card reader and not with the device vendors at the stadium are supposed to use, the Miami Herald reported, citing the police report.

A short time later, the fan received an alert from his bank notifying him of the costly charge to his card, the paper reported. It also displayed the vendor’s name.

The two beers at Hard Rock Stadium in Miami should have cost the fan about $19.

Collier was taken into custody without incident, WPLG-TV reported. Police said he had a Square credit card reader in his possession.

Collier was not working for the Hard Rock Stadium’s concessioner or the Dolphins, according to the Herald. His employer was a Kentucky company that employs “walking vendors” at major sporting events and concerts.

“Our onsite supervisor contacted the authorities immediately upon learning of the overcharge on what was Mr. Collier’s unauthorized personal device,” the company told the paper.

Online court records show Collier was booked into the Miami-Dade County jail Monday on charges of grand theft and possession of a skimming device.

The expensive beers may have helped the fan drown his sorrows. The Dolphins lost to the Los Angeles Chargers to remain winless for the year.
