1. I do not understand “What time do you close?” “How's that?”
2. why “I'm glad I don't work in a store.” “How's that?” “Because I wouldn't want to have to deal with customers all day.” “If you were planning on looking at the place today, you may be disappointed.” “How's that?”
Also, how's that again. What did you say? Please repeat it. For example, How's that? I didn't quite hear you.
