@Scarlet 200%: Not really...she's asking for batteries, and the word for battery in Thai is just happens to be the same word as coal...(if we don't use transliterated word, that is...)
Oh, you're right. They do burn really great.Looks like it ran out.I got them.Hey, Kaito. Would you go buy some batteries for me?What took you so long?Took me a while to get these. These ones burn really great, so no worries.
The word for 'Charcoal' and 'Battery' in Thai are both pronounced "taan".
