I was lost and visiting the area and the attendants were very helpful and even drew out a map guiding me in the right directions.
BTW the washrooms were the cleanest I have seen for a gas station.
As a tourist, travelling to Caledon, I was appalled by the service here. Very rude attendant refused to accept my visa, visa gift card, and debit card. She would only accept my US cash. I purchased $75 worth of gas, and she demanded $80 US for the transaction. This has left a very bad taste in my mouth, and I will refuse to travel this route in the future.
Esso and the BBB have been informed. I only hope others don't experience the same level of service in the future.
