They protested when they couldn't pay it back.
Furthermore, you do realise that the Greek bailout was just a bank bailout in disguise, right?

"Since the Greek debt crisis began in 2010, the southern European country has received two bailouts from international creditors and is currently on its third. During the first two "adjustment programs," as they're known in bureaucratic parlance, Athens received some 216 billion euros.
Of that amount, the ESMT's study found that 86.9 billion went toward debt repayments, including 9.1 billion in repayments to the International Monetary Fund (IMF), 52.3 billion was spent on interest payments, 37.3 billion was used for bank recapitalization and 29.7 billion was doled out to provide incentives for investors to get involved in the private sector.
Only 9.7 billion euros, according to ESMT, was directly contributed to Greece's fiscal budget or to kickstart the Greek economy."
What I said, they didn't protest when Greece took that money.
That the money given to them was for paying back the debt of Greece against banks is nothing new.
The problem of Greece at that time was not to 'kickstart the Greek economy'. They needed money to survive the weeks and days.
I doubt Greece wanted to go that route, once it was clear to them what was about to happen. Actually the left wing government had to learn it quickly that semli-democratic decisions about other people's money is worthless, when one needs even more money. And they did.
That's a very simplistic view. If Germany would actually control the Euro, the ECB (European Central Bank) monetary policy would look quite a bit different.
Greece didn't protest when they took the money. They protested when they had to pay it back and called that 'undemocratic'.
