Ha-ha. That question is valid only if you were the one who planted it.

Seriously, though, try to put yourself in the customer's place. It's a
valid question, stemming from interest and curiosity, probably, rather than
haggling strategy. A reasonable answer would be, "It varies a lot,
depending on the bowl, and a lot of factors--could go from half a day to a
week, sometimes."
