Dave Mustaine has engaged in many a feud during his career. Metallica, specifically James Hetfield and Lars Ulrich, circa 1983. Mike Muir of Suicidal Tendencies. Kerry King of Slayer. His record labels. Those have been his nemeses in feuds. He certainly doesn't back down from a war of words or a battle of wits.

Mustaine's latest target? Men's Warehouse.

Yes, the clothing retailer.

Why, oh why has the discount clothes store incited Mustaine's infamous ire? According to our friends at MetalSucks.net, the Megadeth mainman doesn't like their choice of words ("guarantee") or their false claims. Turns out he's a disgruntled customer.

Below is the Megadeth frontman's open letter to fans, posted on Facebook, about his displeasure with Men's Warehouse, which was tardy in delivering a gift certificate to his tour manager. He felt compelled to voice his disgust and get it off his chest. In fact, he won't ever step foot in the store ever again, whether or not he needs a suit for a court date or a funeral, or if he is seeking shelter from a blizzard.

That's a serious line drawn in the sand, er, snow.

"Droogies,

I know that not all of you have the kind of job that requires a suit, or wear a suit when you (if you) go to any kind of faith-based service, court date, wedding or funeral, but if you do...you are going to want to read this. You know me, I don't complain much in writing, but I gotta get this off my chest.

A few days before Christmas I purchased a gift certificate from the Men's Warehouse in Salt Lake City, Utah as a gift for our awesome tour manager Jim Carroccio. You know the Men's Warehouse...the old geezer with the voice that sound like he has chain-smoked since he was a fetus; the one that espouses, "I absolutely guarantee you're gonna like the way you look," or some manure like that, right?

Well, I was talking to Jim today and wondering why he didn't say anything (I think we all wonder sometimes when our loved ones or friends get gifts if they actually like them) and it turns out that they decided to hold my order, otherwise called by them as "pending," and told no one. For almost 9 days now I have been waiting for delivery of this gift certificate, and I wouldn't say anything because it IS the holidays, but these salesmen promised that they would GUARANTEE a two-day delivery of the certificate to Jim (it seems they throw this word GUARANTEE around quite a lot).

So, we called and asked what happened and they have no explanation whatsoever, they didn't care, and when we asked if they were going to do anything to remedy this, they made no effort whatsoever for this mix-up...although they did promise me the same GUARANTEE that they gave me when I bought it; that is that they will send it "two-day delivery," but I already was promised this. Maybe they mean 12 day delivery.

I really think that it sucks when people make false claims, that they don't care to make good on a problem that is clearly their fault, and with all of the "ABSOLUTELY GUARANTEE IT" crap I just had to say something. We are all living in very tight financial times right now, and like I said, you may not wear a suit for your job or for an event or occasion, but if you do, I would strongly recommend you wear someone else's suits. Go to Jos. A Bank instead. I for one, will never set foot in a Men's Warehouse, even for shelter from a blizzard.

I absolutely GUARANTEE it.

Dave Mustaine"
