Paying By Check

So one of our customers comes in to drop off a check, and she walks in and says, "do you have an envelope?"

So I hand her an envelope.

She puts the check in the envelope, writes our company name on the envelope, and hands it to me...

I'm the person who enters the checks into the system. There is really no need for an envelope with our name on it. You're here... we know who you're giving the check to. This isn't the USPS.
