That's the inevitable outcome of this type of behavior. Like so many startup's attempts to squeeze customers in the short term, it works for a small window of time but leads to longer term consequences that are never properly accounted for.

For most tech workers an extra 20% on top of everything else is not that big of a deal, but for anyone who saves up for a night out that can be a big upset.
