This is a pet peeve. I absolutely cannot stand it when people are not readily armed with a BART ticket in hand BEFORE they approach the ticket turnstiles. I hate it when people stand in front of it, blocking it, while digging through their purse or computer case endlessly for a ticket. They search for 5 second, and then slowly realize that oh, they don't have one, causing a long line of people waiting behind them to get through. I also cannot stand it when people don't realize in advance that their tickets do not have enough $$ value to get through the gate. Instead, they try again and again AND AGAIN, while blocking a line of passengers behind.
With BART, every second counts. If I'm delayed for 15 seconds let's say, it could cause me to miss a train. Instead of running through the doors before closing, I'd be watching the train just leaving the station.
Yes, I am impatient. I move fast through the parking lot, through the ticket turnstiles, up the stairs and into the train. I do not allow myself any step of inefficiency and expect others to do the same. 90% of daily commuters are like me. But the other 10% somehow find themselves hovering around the ticket turnstiles, ticket machines and escalators like they've never taken BART before. If they are first timers, they can be excused, but some of these folks I see daily.
