Tourist guides and drivers from hotels and companies, however big and established, might be earning large commisions from most shops in Colombo, whether they be government or private. It is therefore advisable not to get your driver to stay with you whilst you do your shopping. It is always better for you to get him to drop you and leave. Tuk tuks can be found around hotels, malls, and other touristy places where they charge tourist rates. It's advisable to get a meter taxi or call a budget taxi, online cabs or fair taxis as they are cheaper. So remember, if you are in a tourist area do not get a cab there but walk away from the area a bit and flag a meter taxi down from the road.
