This happened at my job. I got fed up, and I started packing my lunch (when I take it) in my softside lunch bag and using an ice pack to keep everything cool until I am ready to eat.
My company used to supply coffee (including flavored coffee), all types of teas, hot chocolate (regular, low sugar and mini marshmallows), and individual ice tea packets.
My ungrateful coworkers began to steal whole boxes of iced tea, herbal tea and even the paper towels that were stocked in the kitchen. As a result, my company now supplies coffee and regualr tea only. The coffee machines use individual packets of coffee which only work with the machines we have at work, so that eliminates the theft. Gone are the iced tea and hot chocolate.
I just don't understand how people do things like that with no remorse. The sense of entitlement some people have is amazing!!!
