Question.......Who really uses mugs anymore except waffle house. lol
No really when I think of someone drinking coffee or a drink in a executive office/ professional setting I think of travel mugs. I know my self I really don't drink much coffee unless its 40 or below and would never consider drinking from something without a lid while driving. Not saying I wouldn't drink from a cup but It would not be my first choice by far. I would think a PM would think the same thing. We/ I dress in jeans ect to work in ......These pm's wear suits and dresses. Last thing they want is to spill something on them, the desk, or in that BMW they are driving. Cups are cheap for a little extra I am sure they would prefer and use and most importantly keep a travel mug with a lid.
