When you have no time to wash your hands but find the time to smoke a cigarette perhaps it is time to re-examine your priorities.

If you were properly vaccinated against Hep A you should be fairly well protected from getting Hep A. (No vaccine is 100% effective.)
"The hepatitis A vaccine is called Havrix or VAQTA. After you get the vaccine, your body learns to attack hepatitis A if you are exposed to it.
This means you are very unlikely to get sick with hepatitis A. Because no vaccine is 100% effective, however, it is still possible to get hepatitis A after you have been completely vaccinated."

If you are still concerned, talk with your doctor.
So if im vaccinated of Hepatitis A...it is mean that im still immuned for the hepatitis A Virus?
You cannot catch Hep C by dropping an item on a dry floor in a bathroom (or anywhere else) and then touching the item. Hep C is spread by blood to blood contact. The blood of someone with Hepatitis has to get into your blood.
Hep A is spread through the feces of a person with Hep A.So if you got feces from a person with Hep A on your hands and then put them in your mouth, Hep A is a possibility. But from your story, that is not what happened.
If you are still worried, get tested to ease your mind.
Also, it is a good idea to wash your hands after going to the bathroom. Washing your hands protects not only you, but it also protects other people from your germs.

I'm not very familiar with Hep-A so I won't attempt to address that portion of your question.
Hep-C is transmitted blood-to-blood. Based on the scenario you described, i don't see a blood-to-blood transfer.
Regarding your comment about hepatitis vaccination, you can be vaccinated against Hep-A & Hep-B, but there is not currently a vaccination against Hep-C. I'm not sure about other forms of hepatitis such as Hep-D & Hep-E.
