At the risk of boring everyone shitless, here's a nice list of all the Africans we know and what they're doing now:-

Kenyan - works on Fresh Produce department at Tesco
Tanzanian - has his own hairdressing business
Gambian - security guard
Nigerian - ditto
Zimbabwean - assistant in John Lewis' men's tailoring department and has now started his own business
Burkina Faso lady - checkout at Tesco
Ghanaian lady -    ditto
Malian - student at UEA
Congolese - two chaps, work in Bernard Matthews
Angolan - works in fresh fish department in Tesco

All these people have successfully made a new life here in UK and are contributing to society, working and paying taxes (apart from the student of course)
None of them have unpleasant habits, cause problems at work or refuse to integrate. They're all lovely people.
