Tim Hortons

I have been coming to the RUH hospital since the end of April. I am a frequent user of this particular Tim's location and we were given a gift card from friends to use during our visits to the hospital! This terminal and when spoke to the employee regarding the non use of it, that I was told it's a technical issue why not only this Tim's but all in this extended building are affected! What kind of service is this to your customers? It is unacceptable that a service that your company sells/promotes leaves their customers hanging? Terrible
