What does "now" mean in Uganda?

Let me give you an example:

07:25 Call 145 to order a taxi, make sure they come immediately, have change and as usual give them all your contact details (why don't they set up a client database?)
07:26 Be dressed because you know that the taxi will be there "immediately, now"....
07:30 Pack your bananas, fruit juices etc
07:31 Rething the selection
07:34 Finally tie selected and bound
07:35 Sort the ties in the wardrobe
07:40 Sort shirts in the wardrobe
07:45 Bored of resorting a sorted wardrobe, so decide to hand over the music CD now instead of in the evening
07:48 Convince the guard that you do not need a visa for the UK but that you just want to hand over a CD to an employee of the Visa Handling Service
07:49 Hand over the CD with the music to a colleague of the acutal recipient, realising that there are a lot of beautiful employees, get angry that as a German you need no visa for the UK, smile, while the guard closes the gate...
07:51 Start waiting outside for the taxi, realising that you should have walked...
08:05 The taxi arrives at the apartment house
08:10 Taxi arrives at the bank and the driver realises that he has no change...

30 minutes = immediately / now ...
