Cheap but effective

I finally have a chance to post a new blog. Been busy with moving to a new home.
One of the things we have been doing lately is eating on the go, i.e., fast food. Something that I have done, although, it sounds cheesy, is to add to my order once I get to the pay window at the drive through. Example: I had ordered my food going to the drive through window. I had already paid in the first window, so what I did was add something once I got my order. About 50% of the time, they just give it to me free. Like, I would order an upsized drink and instead of charging me the difference, they just give it to me free. This sounds cheap, but it is a good way of upsizing your order or getting some extra food with your order for free.

It doesn't hurt to ask. All they can say is no or it will cost you extra. This is just a simple idea.
