I would look over the above link before jumping into your next cab.
Cabbies are scammers everywhere in any country.
I'll never forget the $90. ride from the airport in Paris to our hotel on the left bank in 1986, my husband was tired and not thinking clearly after the long flight, when he realized we had gone around in a huge circle for the 3rd time, he told the cabbie to get it together, what a scam.
You should always ask the driver for a approximate cost before sitting inside any cab.
We learned the hard way many times, even in Boston the cabbie took us on a long haul, we had to scream at him to just stop the darn cab and let us out, he was abusing us with his long way around the city.
My husband actually worked for Fo Taxi back in the late 1960's when it was more honest, the drivers were professionals who wore uniforms , suits and ties and actually had regulations to follow.
Different world, different time.
We asked how much a cab was last summer for a short ride from the Octagon to the city park, my husband speaks perfect Hungarian and the cabbies didn't want to even give him a quote, they said they were on a break, no way, they just didn't want a short ride with a local, looking for a tourist to scam. We finally found a new driver who didn't know the routine and gave us a honest quote, gave us a ride and he got his tip as should be.
My husband also was a cabbie off and on for 7 years in Las Vegas, great part-time job he would quit after 6 months when we returned to Hungary for holiday, was rehired 5 times with the same co. No reports of him ever mistreating any clients etc.
He said many of his fellow drivers were just " trashy" they would take tourists in Vegas on the Arterial without first asking them, there was a huge extra fee on the tab to use that one short cut road.
He would always ask first, most people said no unless they really were in a rush to get to the airport.Always told them it was extra, not going into his pocket but to the cab co. directly, those drivers in Vegas only get a percentage of the meter, tips and taking people to strip clubs is the real bread and butter, no one works for the meter pay alone.
We notice so many cabbies sitting out near Keliti on chairs, very odd,like they are just waiting for the right person to devour.
Not sure about charges for huge bags, if there is room in the trunk/boot of the cab then it shouldn't be extra, heavy bags though should warrant a larger tip, hernias are common in drivers from lifting all those extra heavy bags women , yes it is usually women who weigh under 120 lbs. who lug around a 90 lb bag expecting others to help them out and then often forgetting to tip.
