I personally do not own a real tank yet. I own 7 kilts, and I'd like for my next one to be a tank. Speed of service will not be one of the deciding factors when I do decide to order it. I will be purchasing my kilt from a quality kilt maker, and if they tell me it's going to be 5 months, well then I'll wait 5 months. Some things in life need not be rushed, and a quality hand sewn 8 yard tank is one of them.

Same thing with pouring a Guinness. I don't want to go to a bar and order a Guinness if they pour it all in one motion. There needs to be a minute waiting after 1/2 the Guinness has been poured.
