Coach Kavanagh has made quite the name for himself over the past number of years - not only with Conor McGregor, who became the first UFC fighter in history to hold two titles in two different weight divisions at the same time, but he's also written a bestselling book and opened his own training facility to help up and coming MMA fighters.
You'd think with all of these accomplishments, John Kavanagh would not get mistaken for anyone else, especially a bus company.

She clearly meant to contact the 'Kavanagh's Coaches' - but somehow got a little confused.
