I don't think this will help as much as they hope it will. In my experience, people are generally incapable of pronouncing anything, even when it is said to their face. My name is Nat, which is about as simple a name as you could ask for. But quite often, I will introduce myself, "Hi, I'm Nat", and the response will be "Nice to meet you, Nate".

Or even worse: When a barista takes my name for my order, I say "Andrey." Usually they'll spell it "Andre" but whatever. Five minutes later, more often than not, they call out "Aubrey." That's reading their own handwriting. You can't explain that. :P
I originally come from Serbia, but I spent the last 14 years in Chile, where most people seemed to choke on my name: Vojislav. When pronounced correctly, it's "voice love", but nobody outside the territory of ex-Yugoslavia knows how to read it correctly.
When it came to buying coffee and stuff like that, I had the choice of explaining my name ad nauseum or adopting an easier one. I decided to call myself "Boris", thanks to telemarketers who would recover from my name by changing it to something they could deal with ;-)
Anyway, that worked quite fine for years and years, until it started failing, ironically at the Starbucks inside a mall with the highest concentration of tourists and immigrants. I would say "Boris" and two times out of five they would write down "Maurice".
The cherry on top inevitable came five minutes later, when a different barista would call out "Mauricio".
Fortunately, I moved before I gave in to temptation to do what a friend of mine did on a regular basis: give "Spongebob" as his name :P
