I don’t think this policy would pass muster under the ADA though.
The guy might not be sufficiently disabled to qualify - but for example if you have a blind person without a smartphone, you can’t tell them they’re out of luck - because you can clearly reasonably accommodate them without causing “undue financial hardship” by giving them tickets at will-call.
> “undue financial hardship”
If they have already moved away from paper tickets for everyone else, now there is financial hardship, not to mention the loss to the team's economic position from scalping. Also smartphones have supported usage by the blind for years, particularly on iOS.
Visually impaired people use smartphones too. If the app isn't supporting the accessibility features of the platform, it should still be held liable under the ADA.
(Unfortunately it won't as was found when Southwest Airlines was sued over this. Congress hasn't updated the ADA to include web sites since the ADA precedes the web and so it wasn't enumerated explicitly. Also unfortunately, the GOP who have never been huge fans of the ADA have blocked any attempts at patching that hole.)
But check out the settings on your iPhone/iPad or Android device. Whole sections dedicated to accessibility, especially for the visually impaired.
Smart phones have had plenty of affordances for blind people. But they didn’t say he was blind or unable to use a smart phone
For that matter, he could/should look into filing an ADA complaint all the same.
I think you’d be hard-pressed to find a blind person / person with low vision without a smartphone these days: they’re a near-essential window into services that aren’t accessible though plain paper.
