I saw this on the Consumerist about a customer who received his e-mail receipt only to see that it said it was signed by "CHIN".
Nice huh?
I guess his first or last name or initials just couldn't suffice because why on earth would someone recognize that they're actually a person with a name?
Glad to hear though that UPS already has taken action with the driver - although it would be nice to know what exactly happened to the driver - and that they have also reached out to the customer to apologize as well (known only as "J" in the article).
