Pronouncing “TANQUERAY”

A common conversation I have with well meaning wait staff and bartenders is as follows:

Roger: “I’ll have a Tanqueray martini straight up with an olive.”
Waiter: “Ok, that’s a TanGERay martini straight up with an olive. No problem.”

I can’t tell you how many times I’ve been “corrected” about its pronunciation. I look at the bottle and it is a Q and not a G, and thought that perhaps the Dutch pronounce their Q’s like G’s.

Resolved to get the question answered once and for all I wrote a customer service person at Tanqueray and got the following reply:

We value consumers such as yourself and we appreciate your enthusiasm. The
correct way to pronounce Tanqueray is Tanker-ray.

I am vindicated.
