Bus Driver - "You can't drink that coffee on the bus."
Me - "I've almost always have coffee in the morning on the bus and none of the drivers have ever said otherwise."
Bus Driver - "The sign clearly says no food or drink on the bus."
Me - "How about I put it in the bag and hold it on my lap until I get to my stop?"
Bus Driver - "You can't bring food or drinks on the bus."
Me - "So, you're telling me if I had to go grocery shopping and had to take the bus, I couldn't bring that food and drinks on the bus because the sign clearly states that there is no food or drinks allowed on the bus?"
Bus Driver - "......."
Me - "That's what I thought."
Small triumphs of wit make me feel better about my day.
