Coffee tumblers that fit?

Sometimes haha, I live right down the street from my job, other times I have a silicone lid I can snap on just about any coffee mug.

 

Yes, up front..

 

haha I give her a hard time about it so whenever I hear of someone else doing the same, I usually give them a hard time too. its more funny now than anything. if shes getting into my truck she'll get halfway to the door, turn around give me an eat shit look, then pour her drink into a different cup with a lid haha
