Where does M16 keep all those bottles of Jack?

Considering she is wearing a dress and the location she is rummaging I would say either magic or her ass. I'm going with magic, having that many bottles stored in your ass may not be that comfortable. But hey what do I know ive never shoved six bottles of Jack in my crack before. And m16's caboose may just be that spacious... The world may never know

Obviously you need to look more shoplifter videos. If slender people can shove more than six coffee jars, two car batteries or four irons into their garments, some bottles should be a breeze.

She's also a robot so she might have a dedicated compartment to smuggle whiskey.
