Discount Bart Tickets

Is there a way to buy a one time Senior Discount ticket on Bart for a round trip from Pleasanton to SFO Airport.
When I checked at the Pleasanton Bart Station they asked us to go and buy a clipper card.
I would think the Bart station should be able to sell these after we show them proof of age.
Anybody experienced this?

Unfortunately, no. The only thing you can buy at BART stations is full-fare paper tickets.

Getting a senior Clipper card is a bit of a hassle. But once you have it, you're set for all future trips:

Previously, the red and green paper discount tickets were sold at places like grocery stores. Those have been phased out.

Thanks ! Also the local WalGreens also could not help. Definitely an inconvenience for seniors who are visiting and want to take BART .
