Then I discovered that the chain Cafe Metro offers really good deals if you order over it's website - $6 instead of $8 for a salad, and you can pay online and just walk in and pick it up. More convenient AND cheaper! So I order online often, then walk half a block to go pick it up. Feel free to ask me more about my exciting life.
There's only one hitch: sometimes I like a little midday ice coffee pick-me-up. The convenience of online lunch shopping is that you can order the ice coffee and select from a menu what kind of milk and sweetener you want.

Although I know from experience that Cafe Metro has Sweet'N Low available at all their locations, there was no option on their site for it:

So I wrote an email to their customer service, with a suggestion that they add Sweet'N Low as an option. A day later, I got a reply from their head of E-Commerce that not only are they going to implement my suggestion right away, but they were also going to give me a coupon for a FREE SANDWICH!
I bet you thought this story was going to be boring right? You had no idea a free sandwich twist was comin' at ya!
Moral of the story is: I guess maybe it's better to politely suggest instead of angrily complain on the void of the internet. Nah....
