While the booking process is easy and straightforward, the experience ultimately comes down to the service provided by the drivers - always potluck. Today I was sorely disappointed: the driver was 15mins early and visibly angry at me when I came downstairs to the door 5mins before he was originally scheduled; for the entire journey he kept sighing and tut-tutting for no apparent reason. My attempts to make small talk were swiftly rebutted by him. It could be that he was having a bad day, or that the roads were unusually busy for a Saturday afternoon; either way, it was not my fault. Not sure if I'll use these guys again.
