When you write an email to a fellow developer stating that he should disable Instant Run to hopefully get rid of a bug he gets and the developer calls you on phone to ask how he can disable Instant Run and you just want to yell at him "SEARCH IN THE SETTINGS YOU DUMBFUCK!" but you keep it cool and just say "open the settings and search for instant run"
and then you see that he might have trouble finding the build variant settings as well so you tell him where it is and you realize that this fellow developer is not a unique snowflake but the fucking average "skill level" employee in this firm.... Did I tell you that I am looking for another job?
