Kinda should be a requirement
I have been a loyal customer for years but the amount of orders that have been late, misdelivered or canceled due to the driver not speaking English is becoming a issue.
I just had a 18 dollar order canceled by a driver who called me speaking Spanish. I told him I couldn't understand him, he hung up and then just sat 8 minutes away with my order for like 15 minutes. I had to call customer service and while on the phone with them, he canceled the order. Customer service tried to call him for a explanation but his phone went to voice-mail. Honestly I feel like he took advantage of me not speaking Spanish to steal my order.
If a delivery is required contact with a customer then I believe the driver should speak English so it can be delivered correctly and on a timely matter.
