We experienced  substantial communication problems..Unfortunately Juma's English was so muddled and full of both grammatical and syntacticl errors that I never quite grasped what he meant to say. Specifically, when it came to discussing pricing, he would name a price which appeared to be inclusive, but then name different costs, sometimes in Kenyan shillings and sometimes US$, so one would be left wondering what was included and what was not or if it was all-inclusive. When one asked him to clarify, he would reply with an equally jumbled incoherent collection of figures in different valuta. I never gained clarity on the finances, and in the end dropped the whole arrangement. We never met.
