I've been having Subway for many years, and I believe it is also a globally renowned brand. I'm giving 5 stars for the Subway leader's customer service (the lady dressed in black). (Sorry, I didn't catch your name!) I was dining in with my family, so we ordered a few sandwiches but only opted for 1 set. She took over at the cashier and gave advice on how to optimise my meal. I ended up paying a cheaper price for more! Thumbs up. Going the extra mile!
