I have fixed lines of code that cost many multiples of this in compute cost. At $previous_company, user-initiated account deletions were only soft deletes, and we were supposed to actually delete data 60 days after the request (in case people regretted their decision). Due to a bug in a SQL query we stopped deleting users (and their associated data) for over six months, racking up over half a million dollars in additional storage cost.
