Let me paint a picture of Africa for everyone.
1st world countries donate millions of tons of clothes to Africa every year. They are put in bails and sent free of charge to all the nations of Africa. Some of the perenniel options include hats, shirts, and jerseys for the losing side of a superbowl or world series.
These infinite supplies of free goods are then intercepted by corrupt politicians and they are then brought by their racket of distributors and dealers to the bazaars located in every large-medium-small city in Africa.
Since they were free clothes to begin with, and only the Africans themselves have stolen the free clothes and converted them into goods with price tags, they finally get sold to the common man at the bazaar. Prices for a new T-shirt typically are $0.50-$1.00 at the final location.
The Africans you engage with in the hunting world can buy all the clothes they want and can afford for $0.50 each, but they cannot afford $0.50 because they are below the poverty line by far. The very best trackers and skinners with fully booked operations will make between $1500-$3000 per year. A sign of the black employee's wealth and success in employment would be the extraordinary ability to have $60 per semeseter, per child, to cover the public school fees and to buy the required school uniform and shoes for their children. Most cannot afford school fees, so their children stay home and work on the farmette, perhaps one day having the ability to sell a goat or a few chickens to come up with the funds to once again re-enroll their children in elementary school.
Knowing the above, think about your tokens and gifts for the people that work for you in Africa. It's akin to spending $4 a bottle on Evian water and bringing it to them as a gift. "water is free here, this guy gave me fancy water, my village is starving and my kids can't afford to go to elementary school".
They don't need or want your clothes. They don't want your knives. They want cash to muster the ability to send their kids to school or buy wire for a chicken cage or a bell for their donkey.
There is nothing that an African wants or needs that you can bring from America that they cannot get for 1/10th the price in their local community.
What they can't get and you have is money. That's what they lack.
I know we want to pretend that Africans are just like us, and I know we want to pretend that western gifts are as well received in Africa as they would be in the USA/UK, but neither are true.
Before you buy a $15 item for an African, realize that that is 1/4th of the money they needed to enroll their kid in school for a semester. Your t-shirt or ballcap is little consolation to these facts of life, but giving them $15 could be life changing.
