RK Bar & Restaurant in Croydon

We ordered two wraps on a Sunday night, were told we couldn't pay by card over the phone and if we wanted to pay by card only one driver had a card machine so it would increase our delivery time to over an hour instead of 40min. Clearly a tactic to encourage people to pay in cash as our order was only £13.00 and we didn't want to wait ages for our meal so agreed to pay cash. Little did we know that in the end we were waiting over 2hrs for delivery and dispite multiple calls to the restaurant we were unable to get any updates on where our meal was until we finally got through to the restaurant and were told the driver could not find our address dispite it being 15min away from the restaurant. 1.5hrs after making the order we were told the driver was 10min away. Further calling and 2h.15min after making the order the driver finally pulls up on our driveway, he parked his car half on the road half on our drive way banged on the door and when answered just stated £13 no apology no hello nothing. I took the food and gave the driver £10 I informed him if he wanted the rest of his money he could get his manager to come and speak to me and at least apologies to me for such terrible customer service and delivery time. At which point the driver tried to snatch the food back from me and started shouting that he is the boss and owner and if I wasn't going to pay full price he would take the food back and throw it away. I replied do you really think over a 2hr wait and no apology or anything is good customer service and the right way to run a business if he was the owner. At which point he stormed off into his car shouting at me that I was banned from his restaurant and then proceed to abuse me in his native young which I assume was Greek. I didn't think the experience could be much worse and then a few minutes later the same person then proceed to blow up my phone with multiple calls shouting down the phone at me that I was "a cheap man" and "banned from his restaurant" he also was asking me if I was English no idea what relevance that had to his argument. He then also tx me abuse afterwards (picture attached) All this over £3 if he is the business owner he clearly needs to go back and have some further lessons on business acumen, customer service and overall advise on how to run a business. He clearly needs the £3 more than me and if he carries on running his business like this then definitely will need all the £3s he can get. Totally disgusting and never again

Grabbed a classic hotdog here when england were playing 16/08 £7 for a cold flaccid monstrosity.
