PMS set-up at my hotel is DUMB

The hotel I currently work at has been open for only a couple of months. There are a few effed up flaws that get on my nerves.

First of all, the screens we use at the front desk were originally intended to be legible only to the front desk agents. The screens were built into the desk with a slant and a blinding-screen over the screen which supposedly makes the screen show nothing but a silver blur to the guests who are opposite the desk.

And... It doesn't work! The people opposite my screen can see everything!

For a few reasons, this situation sucks de-ox.
For one thing:
If a random stranger comes in and asks if Joe Shmo is in, we look up "Shmo" in the property management system, and the person opposite us can see (if he knows where to look) what room number Joe is in.
For another thing:
How am I supposed to charge walk-ins crazy fees if they can see what the default charge is? It's hard for me to say that a room is $209, when the computer shows $189 (or if you can read backwards and upside-down "681$")

When we first opened, and all we could see was a couple of square holes in the marble front desk, we were told that guests opposite the front-desk agents wouldn't be able to see the screen. But after installation, the only people who are blind to the screen are the front-desk agents to your left and right. Oops!!!

Not to mention our property management system which is full of flaws. WinPM. I thought it would be better than Jaguar, but such is not the case. They're both effed up. But I'll write about that in another post.
