Other concerns with the Commonwealth Games in Delhi aside, some are making the biggest complaint about the snakes. A South African athlete had a surprise in his room, and the teams are expressing concerns over safety.
From Yahoo News:

A South African athlete discovered the unwelcome guest in their room and the South African High Commissioner Harris Mbulelo has admitted he is now worried about the Games.

"We have very grave concerns," Mbulelo told the Press Trust of India news agency.

"If snakes are found we can't ask our teams to stay there."

From an interview an an ABC article, the Aussies put a lighter spin on it:

JOHN TAYLOR: And an unexpected hazard has emerged for India's organisers. Indian media is reporting that the South African team found a snake in one of its rooms in the athletes' village. And the Times of India newspaper carried a front page photo today of a man removing a one metre long Cobra from the Tennis Stadium.

STEVE MONEGHETTI: You don't want to see one. We come from the country got the most venomous snakes in the world so if any country is prepared it's probably us. Maybe we've planted a couple, I'm not sure, what sort were they? Did you get the identification of them?

REPORTER: Cobra.

STEVE MONEGHETTI: Cobras. Right, okay. Maybe, maybe, yeah well, its only a Cobra. What are we worried about?

MARK COLVIN: Well maybe just bring in some Mongeese.

With all the other problems, I think at this point they are just looking for something else to pile on.
