I have colleagues that enjoy only drinking, nothing wrong so far but those guys are ordering a lot of crates monthly on the company budget.

You can see it as part of the fun or making the workplace enjoyable, what's wrong with having some relaxed atmosphere?

The funny fact that each developer has an education budget and guess what? you can't even claim it, the manager said no to conferences, if you want to get a book or training he will come up with 1000 excuses.

So when the company priority is spending thousands on drinks and ignore education and growth don't expect the motivated developers to stick longer.
