singles bar

I'm a little stuck... Click here to teach me more about this clue!

'where one's picked up a' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'blessing in disguise right?' is the wordplay.
I cannot quite see how this works, but
an anagram of 'blessing' is 'singlesb' which is located in the answer.
'right?' could be 'ar' (I've seen this in other clues) and 'ar' is located in the answer.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for singles bar that I've seen before include "Place for picking up" , "Meeting-place" , "ban on certain records?" .)
