I am in Rome now, just had lunch earlier. The waiter brings me the bill and asks,"will you be paying your tip with your credit card or cash?" He asks me this twice and tells me that if he does not see the cash then he'll put the tip on the card. I've been here 5 days and this is the 4th time I get asked this question. Very tricky! Not matter how good the food ever is, this leaves a very bad taste in my mouth. Of course, I do not leave a tip.
Oh and the Taxi drivers! They are crooks! Beware. I've had taxi drivers to me that they cannot use the meter in Central Rome. Luckily, I know that is a lie, so I immediately get off the cab. One of the taxi drivers put his car in reverse i was getting off and stepped on the gas as I was getting off causing me to fall on the ground then he sped off as he called me a bad word.
Other cabs, I have paid very high amounts with the meter going very fast. I got back to my place and googled fast meters in Rome and discovered that the taxi drivers put on the tariff 2 that should only be used out of Rome to make it go fast. Now I watch the meter to be sure it is on 1 and it is but by the time I arrive it has been changed to 2. I am now solely taking buses. Not an easy public transportation system to figure out for visitors.
