Dispicable behavior by Shell staff

Absolutely appalled by the service I received from this place. Attendants that were so rude and disrespectful. Shouting and swearing at a customer that was upset for waiting so long to fill up, and they were just walking by to have their breakfast. What is this? I don't have to deal with this **** when there are other places I can go to, to receive better service. Places like Total, and Engen. Never again will they see me at Shell. Absolutely revolting.
