oh hey, I can't bring a cup from home and be drinking out of it except on my half an hour break..and that could be anywhere from an hour or hour and a half of just getting to work or a couple hours..we get our breaks when its convinient because of business and number of people and who all needs breaks..i've been sent on break less than an hour after getting to work..but no smothies..more simple stuff.. I do have glass containers with snap lids I could use for things. and I carra backpack..and I have pockets I could but a little bit in..
