That's smart and well executed. Congratulations

I completely agree chatbots can be slow at collecting information. In the case of Melon Post we look at rivaling the speed of a web form at least with orders to a previously used address. At this point, the benefit of being available from your message box and focus on simplicity will hopefully attract it's own little group of loyal customers!

In most cases various error messages for a certain position in the conversation are available. These messages are aimed at nudging the user back into one of the predefined conversational flows or to have them repeat their answer in a different format.

Something the bot still has trouble with is if the user sends a second reply before the answer of the bot is received.
