When it comes to Chipotle Mexican Grill (NYSE: CMG), you could say my timing hasn't been impeccable. I got impatient and bought stakes in Chipotle for my real-money portfolio twice in recent months (check here and here), and lo and behold, the stock price has finally receded by a long shot. In fact, Chipotle's shares got absolutely walloped over just a few days this past week. Whoops.

Last week's quarterly report caused more panic at the bistro than ever. However, even though customer traffic has slowed, Chipotle's quarter didn't lack spice by any stretch. The burrito slinger's profit surged 61%; its total revenue grew a healthy 21%. Same-store sales may have missed analysts' estimates, but heck, Chipotle's 8% increase in quarterly comps is still incredibly impressive in the current economic environment.

Chipotle's culinary and pecuniary misery has company, too. Former parent McDonald's (NYSE: MCD) has been a very strong restaurant performer for ages now, but the fast-food leader recently reported its own disappointing quarter, with a decreased profit.

Right now, the panic is palpable: Investors are shunning companies that rely on consumers spending on things they like to have, but possibly don't need to have, like dining out or pricier foodstuffs. Whole Foods Market (Nasdaq: WFM), another stock purchased for my real-money portfolio, has experienced a plunge in stock price partially on speculation that it could follow in Chipotle's supposedly abjectly disappointing footsteps when it reports quarterly results.

More drama: Is the new Cantina Bell menu from Yum! Brands' (NYSE: YUM) Taco Bell going to take Chipotle out? And holy cow, what's going to happen to another premium-priced quick-serve stock, Panera Bread (Nasdaq: PNRA)?

Right now, anything goes when it comes to pessimistic scenarios about stocks like Chipotle. The sky and stock prices are falling.  

That's why we need take a deep breath and count to 10. My timing on Chipotle may not seem impeccable right now, but here's the thing: Nobody really can perfectly predict or time things in the market. Macroeconomically speaking, the world's a mess, and the American consumer's beleaguered and pinching pennies. Regardless, long-term investors will accept times like these as buying opportunities, and if they've already bought shares of the best companies out there (and I consider Chipotle to be one), then they'll hold on tight and ride this out.

Time will tell, but high-quality companies will survive and thrive over the long haul.
