Just went to the Pioneer station on Howard near Highway 3. The cashier was so incredibly nice, there was a problem with my chip (eventually it worked, touchy machine!) but each time I tried she just would say try again sweetie, and even the small talk while waiting for the transaction to go through was very sincere. It may be a few minutes out of someones' day but the interaction was very kind (yes, I did tell her she was very nice as well)
