My son bought a ticket to a concert ...they don't post out tickets...they don't even send you tickets by email that you have to print out yourself...that save them money...NO...they just give you an image on your phone that you show when you go in...my son has to go in for an operation on the same day...SORRY YOU CANNOT SELL THE TICKET YOU OWN TO ANYONE ELSE...anyone else trying to use your ticket on their phone will be detected and refused entry...that is THEFT...and they are using your own technology against you...what do you think?..how many other ways are they going to rip you off in future...
