Belgian Waffle Q

At the belgian waffles Q ...

Gf was queuing ...
Bf came along. Asking her to sit while he q and buy.
Gf says it was okay. Bf q along with her but then he went off somewhere after a while.

A while later, he came back.

Bf "I saw who and who over there." *Then hinting in a subtle way, whether want to join them*
Gf "They saw you ? Did you say hello ?"
Bf "Acknowledge Yes in a sort of manner"
Gf "Why don't you go over and join them ? I buy already then come over."

Then started a string of "You go join them lah" "Don't need lah. I can ask them out next time" thingie of conversations. It sounded awkward as it dragged on.

I think it concluded that they won't join his friends.
