The intercept is 1.9575 minutes which implies that on an average a person needs to wait for 1.9575 minutes if he ordered 0 items (no item).
This doesn't make sense in real life scenario because if there is no item ordered why would someone wait. So, the intercept here doesn't make sense.
I hope this will help. Thank you.
