Mugg & Bean - Watered down coffee

I visited the M&B at the OR Tambo International airport on the first floor. i ordered the coffee and my daughter ordered something to eat. i must say the coffee was the worst i have ever had. from M&B and anywhere else. it left a bad taste in my mouth, literally. it was very watered down with no to little coffee flavour. the waiter that saw to us was a bit unsure about the orders he was taking initially. even when trying to call him during our meal he was distracted with his team mates at the entrance. i had to speak to someone else. i really do enjoy eating at M&B but this was truly the worst tasting coffee i've ever had. please improve your coffee.
