Zach managed to order Fred and himself another pint while making sure no one took the seat. It was a little comment but easy enough, and Zach was having tons of fun flirting with him. He wasn't sure if Fred got that it was flirting or...well, he wasn't sure. But Zach didn't care to analyze it. He was having fun either way. Fred was loads of fun, no matter what happened.
The door to the loo opened, and Zach looked over, mental checklist going off. Yep, Fred was back. Smiling, Zach raised his new pint in greeting. And as he came closer, he spoke again, "Seat saved, as requested."
