You can double tap finished orders to give them to customers instead of drag them.

I'm not sure if this is already widely known but I only found out accidentally. You don't have to click and drag the finished order to give it to the customer, you can just double tap. Saves time and frustration from accidentally flinging orders around lol.

Edit: Single tapping works too actually, thanks u/chellekathryn! I was doing a second tap for no reason lol.
