Nah. If you're going to buy a person a ticket to the show, you buy them 2 tickets. 9 times out of 10, they will invite you to take the second one. Conversely, just get them a pre-paid Visa or cash in the amount of the ticket with a note saying (Maybe you can use this to buy a ticket to X show), and then they can decide if that is something they would want to doon their own, or find someone else to go with.
