TB Xray Immigration Fail

Waited more than 6 hours for a TB Xray for UK immigration. This Nairobi Kenya process is flawed. I lost 6000 in income revenue just being here, 2500 in paying for this, and it's not like I live just around the corner. In addition I have lost money on the UK visa appointment. To make matters worse, Xray department says they are independent of the doctor, and they can't do anything and the doctor says they can't do anything about the wait. Obviously this whole process is flawed. This is on TOP of having to wait for three weeks for an appointment. I am so very unhappy about all this. With all this modern technology this should have been a walk in service, 30 minutes with biometric enrollment, Xray and TB free certificate. It feels like a government institution!!
