I rented a car again in Avis.
The little brother in the Calgary store is very warm and friendly and does not recommend any additional charges. I got the booked model, the car was in good condition, clean and tidy.
When returning the car, the staff pointed to a small point on the front glass and asked if the damage occurred during the rental of the car? We told that it existed at the time of the rental, but Avis was not marked in the contract. The other party looked at it again and said "Ok, send the receipt to you email", and we left after saying goodbye to each other, ending this pleasant Calgary and Banff, Jasper National Park trip.
I will rent a car at Avis next time, the price is reasonable and the service is good.
