Rat thoughts

A week or so ago, I complained to McDonald's about how their employees could only get my coffee order correct 25% of the time (they're up to 40% now).  Today I found in my mailbox a letter of apology and a bunch of coupons.   One free large sandwich, one free Dollar Menu item and 2 free medium "Extra Value" meals.

I guess if they're free, then they're an extra Extra Value.

The coupons have shiny color-shifting foil and a notice to the restaurant to verify the authenticity of the coupon with the foil seal.  I guess they had a problem with counterfeit coupons?

Continuing to look through the fine print, it says "Prices may vary".  I didn't know that the price of free could vary.

Anyone else here use Weather Underground?

I've noticed a peculiarity in their weather photos section.  If I try to give a photo a low score, it totally ignores my vote.  It will give me the "Already rated" screen, but it won't change the current rating nor will it advance the number of times the image has been rated.

I tried e-mailing the photo admin there, but never heard anything back.

Is this a bug?  Do they have some system where they throw out the highest and lowest votes, like in figure skating?  Or do they just ignore low votes in some touchy-feely-don't-hurt-anyone's-feelings kind of thing?
