Adults wearing pajamas around town

I saw a post earlier about wearing a bikini top around town and it made me think about this common sight - adults wearing pajamas to town, shopping, banking, casual errands. 
How do you feel about it and why? 
I worked at a bank for 11yrs and we saw this all the time from all different age groups. Adults would come in at all hours of the day and sit in our office and handle serious banking issues. 
For me, that's just very tacky. I don't want to see that you just rolled out of bed, pls go use the drive-thru. But it's become so common to see adults in pajamas around town, even slippers!
