Hotel Hoppa- Unacceptable, and aggressively rude service.… A group of us used Hotel Hoppa transport between Heathrow Terminal 5 and Terminal 5 Hilton Hotel, in early June 2022. The electronic scanning system on the bus only accepted three out of our five electronic tickets, which were all on my phone. The driver wanted to charge me a cash payment for the other two tickets! I refused to pay again, and offered to show him the order email proving I had paid for 5 tickets. At this point he screamed at me to go on, and stop wasting his time! This rude, aggressive, and unprovoked behaviour is, of course, totally unacceptable, and he refused to give me his name on my leaving the bus at the Hilton hotel. On my groups outward journey in late May, it had also proved impossible for the electronic scanning system on that bus to validate all five electronic tickets on my phone. However, the driver on that occasion, politely allowed my group to all enter the bus, on my showing him the order confirmation email. The return drivers aggressive and rude behaviour, coupled with the incompetent electronic ticket scanning equipment on Hoppa buses, caused both myself, and fellow travellers in my group unnecessary stress, friction, and upset. Consequently, none of us will be using the services of Hotel Hoppa again!
