Who is twisting the truth?

You yourself have confirmed that the grand claim of leaving with 4500usd in your pocket is misleading as this actually represents what a couple leaving together would receive.

In essence your job ad reads like that of hotel.

Stay at our luxury 5star hotel for as little as ### a night. It looks like a great deal until you read the disclaimer and find it's based on 2 people sharing, arriving in the off season and staying more than 4 nights.

I can understand why you put a big figure like that in the heading of your ad when it is posted on a site like Dave's alongside dozens of other schools all offering just about the same as yours. Just like the hotel ad you want to grab people's attention and you hope they miss the finer details at the bottom of the page at least until you get them on the hook.

When reading job ads teachers just need to stick to the age old rule of 'if it sounds to good to be true, then it probably isn't'
