Costa Coffee in East Hertfordshire

Waited approximately 20min to be served. Ordered coffee & food £9.05 and the staff looked surprisingly l gave cash. They informed me that they had no change of 95p and sent the manager out to find some money. Manager returned after 10mins with no change. So after nearly 1/2hour l asked for my money back. Back to Costa Broxbourne which is 10 out of 10!
