A friend of mine told me that he's been seeing unfinished BART tickets being left around at stations. The amount on the tickets range from 50 cents to $3. I've seen abandoned tickets too. Sometimes they are left on top of the turnstiles, other times they are left by the ticket machines, or just dropped on the ground.
Are people too lazy to insert the amount of money needed to get them home? Or is the remaining amount so insignificant to them that they don't mind just tossing it? Or do they want to save someone else a few bucks and make their day?? I think it's all of the above?
I save up my small amount tickets for donations later but I guess leaving it for someone else to use is serving a similar purpose....kind of. I receive monthly commuter checks so I choose not to take the time to insert the remaining amount needed to get me to my destination. Lining up and then inserting the right amount will probably make me miss my train....since I always only have a few seconds to spare. From the commuter checks, I have collected a small stack of large amount BART tickets waiting to be used...so I can see why people some people would leave their tickets instead of finishing up the amount themselves. Am I lazy? Yeah, I admit it. Too rushed? Definitely! Arrogance? Not really. $2 can buy a greasy but good meal at Jack in the Box!
As long as someone is using or collecting these abandoned tickets and they are not just being thrown away, I think it's fine! Some people might not care about $2.20 but I'm sure there are people who would be happy to pick up a partially free ticket and save that money to buy candy for their kids.
I always recommend saving the small amounts and just donate it!
