SeniorDev: "If we were only allowed to use C# 6 features, we could reduce our code base by 30%"
- other devs nodding their heads in agreement -
Me: "So, are you going to change our entire code base to be C# 6 compliant?"
SeniorDev: "Uh, oh hell no."
Me: "So those C# 6 features are going to reduce our code base by 0%?"

SeniorDev turns around without saying a word.

Getting a bit awkwardly quiet now. Better watch my back.
