Nandos Lagos Dozing Away?

I am a huge fan of Nandos (UK). I love their chicken, corn, garlic bread, their perinaise and the restaurant as a whole. Since the day I started a relationship with Nandos (UK) I have fallen in love with it over and over again and the love hasn’t failed, though sometimes I would have to wait several minutes to get a free table at the restaurant even that never affected my relationship with Nandos. This was why when Nandos opened in Lagos, Nigeria I was over the moon. Unfortunately, there was something about the Nandos in Lagos that wasn’t right, though I couldn’t place my finger on what it was, it was certain that the Nandos in the UK was far better than the one over here. I don’t know if it had something to do with the food being too expensive or the chicken served being too skinny, something wasn’t right and it wasn’t only me that noticed this because soon after they opened they started losing customers and the restaurants became scanty and scantier as we the customers were being served with not too fresh bun(I don’t want to call it stale). One day I saw metal chains on the front door of the branch that I visited the most, it was locked up for a long time until it finally closed down. Whenever I remember that branch I always wonder what happened there. Another branch closed down, then another branch.
About a month ago, I went to the cinema and was too early for my movie so I decided to give Nando’s a try. I walked in, ordered my food and was about to find myself a seat but everywhere was dirty and all the tables that were vacant still had used plates, cups and tissues on them. The cleaner saw me looking confused because I didn’t know where exactly I was to sit, he decided to wipe a table clean for me, I sat down and was irritated by the sight of the somewhat wet table in front of me in disgust I got up and went to another table. The same cleaner again came to wipe the table, this time it was manageable not clean but manageable (I still couldn’t stand it, I got some tissue and wiped it clean myself. I caught the cleaner looking at me with the corner of his eyes but i didn't really care). A few minutes later my brother brought to my attention that the same cleaner was the waiter, so at that branch and at the time we were there, the guy who was cleaning the table worked as the cleaner and waiter. As he cleared a table, he hurried to bring a customer’s order and before he could clean another table another customer’s order needed to be served. At a point, the man looked very exhausted. it was ridiculous that he was doing all that work by himself, no wonder the place was filthy.
I left the place not knowing what to think… is this a way to cut down on cost or are they trying to cut down on customers?
