I bought a coffee and cookie and sat down with by book to eat it at a table outside.
A few minutes later a couple came in, bought their drinks, stared at me as if I'd done something wrong and then asked if they could sit at my table with me (as it was the only one in the sun).
I was confused ....all the other tables were empty.
AIBU to say no? I didn't want to awkwardly sit there reading by book but pretending not to be able to hear their conversation. I could have moved one of the ones in the shade into the sun, but I was confused about why they didn't just do that themselves since I was already sat down and settled in.
