That was a rude reminder here as well. 20 years in the service serving hither and yon and another 8 years here in SV, all the while banking with the one institution by phone, mail, and lately, internet.
We financed a new (to us) car and needed to go the CU to sign the paperwork last week. Like you, I had forgotten what it was like...I hadn't been inside an actual branch office in nearly 6 years!
LOL! There are so many people in a branch office. And you have to wait in lines!!! Sitting at my computer is soooo much easier.
