Alice Twain wrote under the heading of "restrooms" that bars are obligated to let you use their restroom but may charge a small fee, 20-30 Euros. Are Euro "cents" shown differently than Euro "dollars"? Right now $1 = .88 Euros. Wouldn't that meant that it would cost about $17 to use the restroom? I ask this because I was curious about people who say that has lunch for 75 Euros. Sounds awfully expensive.

If that's exactly how she wrote it, the problem is that the comma goes with the price, it's not a punctuation mark. At least I would presume, that's the way it is in France, although to be clear you usually see it with a zero in front of the comma.
This is 15 euro cents:

0,15 ?

I have also seen it just written as I did above "15 euro cents"

um, that question mark was a euro symbol originally, Fodors won't allow some characters

First of all, there are no "Euro dollars." They're euros, period (and Europeans may rightfully be offended if you refer to them as Euro dollars). There are 100 "cents" in a euro. I didn't read the post, but if Alice Twain said there would be a fee of 20-30 euros, surely she meant 20-30 cents. Finally, if $1.00 = .88 euros, and the cost to use a European bathroom were 20 cents, the cost to you in dollars would be about 22 1/2 cents (pennies), not $17!!

Alice did actually apologise further down the thread and say that she had meant cents.

f64club,

If you would read the entire post, Alice Twain reposted with the correct explanation. It's eurocents.

Curious

For the most part I like having to pay. I have found for example in Paris when I paid I got a very clean restroom. We have had to pay over most of Europe.

Thanks to everyone for clarifying this (although some were a little more hostile than others, I got the idea). I was mostly curious about how I (having never traveled to Europe) would know whether the writer meant Euros or Euro cents when pricing something.
