Cheeky Chiquito's

Why do we always have the same lame, "templated" attitude from any Customer Services Corporation?

I know this one starts with a rant and it involves the restaurant chain Chiquito. It all started when my 15 year old daughter went for a meal last Sunday to celebrate the anniversary of a friend. When I picked her she told me the story that I duly conveyed to Chiquito. Here it goes:

This episode was told by my 15-year-old daughter yesterday when I went to pick her up after a meal in Chiquito’s Ashton. 
They went to celebrate an anniversary (a group of six girls I believe). They had their meal, all was fine until the bill arrived. They all knew what they ate, what their personal bill was going to be. However, when they added their totals, they were always short. They took a long time to ascertain what was wrong, until someone spotted a “service charge” of £15?

So… they raided their pockets for an extra sum until the total was met. They gave the amount to the waiter(ess?) and as it was more than the total bill, waited for their change… and waited… no one came and after 20 minutes left the restaurant… ungreeted at the exit. 

You know how shy teenagers are… you just did the proverbial “taking candy of a baby’s mouth” and for that… shame on you. 
I think you get the gist of my frustration and how the restaurant took advantage of the inexperience of the children that were paying for that meal.

Chiquito took 3 days!!! to reply... and did it with (un)expected dimwittedness and meaningless corporate vocabulary. I attach a screen print for your review.

Can you spot the major failure? They charged children without warning them, a no compulsory charge (no news there) and as a "gesture of goodwill" they are giving me a voucher for the amount that they should not have charged in the first place, so no loss there, plus... they want it back! I have to got to Chiquito to use the money that wasn't theirs to start with on their produce. No! Those £15.00 belong to the girls and to be used wherever they like. It is called Money!

If you Chiquito want to have a genuine gesture of good will, invite the entire party for a free meal sometime soon.
