I've been cautiously skeptical of everything I've seen either out of professional curiosity or as a user; I thought most of what I see is incremental and adds a little, but not that much value. My final real-world use of one of these simultaneously proves and disproves my opinion.
I was walking back home, when I saw this sign, so I checked-in via Foursquareat this place, realized I could get a small ice-cream for 2 bucks... and so I did.
- I really didn't want ice-cream then
- and I really, really don't like tasti D-lite much anyway!
