[Sorry Gokudera, Heizou is definitely chuckling a little bit at the beer mishap. At least he also looks a little sympathetic!] Careful there!

[He at least settles quickly enough, pulling out a handkerchief and offering it to the teen. It's not much, but maybe every little bit helps?]

Unfortunately, I'm afraid I don't know what a man-uh-tee is either. They must be quite commonplace contraptions for you to be so surprised!
