According to the signage, it's $3 to cash a check. It cost me $9 to send $150 cash.
I have the luxury of saying "ok good. It's only $9"
To a poor person, $9 might keep the power company from shutting off the lights for a day or two. It will get you to work and back a couple times on the bus. It would feed a large family a humble meal.
$3 is almost a round trip bus ticket.
