Andre Johnson is very angry with Wal-Mart. Not because they sell cheap merchandise, or because the greeters haven’t been as cheerful to him – but because they wouldn’t give water to some poor kids.

TMZ hears from the Texans receiver that the retail giant apparently decided not to donate refreshment to a recent charity event of his – all because Johnson didn’t buy enough bikes:

Johnson ordered 750 bicycles to be given to underprivileged kids at an event sponsored by the Andre Johnson Foundation — in return for the purchase, Wal-Mart agreed to donate water and ice for the May 3 event.

But there was a problem with the order, so Johnson ended up buying fewer bikes than planned. Wal-Mart countered by not giving the water and ice as promised.

So, deny poor children water, just because Johnson fell a few Schwinns short of his order? Was Andre requesting Evian or Perrier or something?

Of course, we expect nothing different from a company that pays minimum wage & offers no health benefits, yet rakes in over $3 billion in quarterly income.

Honestly, how hard is it to give a little H2O for a good cause?
