They explicitly ask for 15% tip at the very least!
This is the first restaurant ever I've eaten at where they ask for more tips than you want to give. I've gone to this place three times now and knew already it was an expensive but tasty restaurant. It ends up being expensive because of the amount of food you get for what you're paying for.
However, my last visit was surprising when I was paying the bill, and the waiter asked me if I wanted to leave 15% tips instead of the 10% I was willing to give. I mean, he was quite insistent, he asked twice since I said no the first time! Is this a good or bad thing? For me it was bad thing, and a very unpleasant moment.
I always give a tip of 10%, no matter the place, no matter the service. I know: this is a controversial subject where you never know how much is too low or too high, regardless of the local customary.
This whole thing made me re-think again: Why should we always leave tips at restaurants? Why don't we give tips at the car wash, at retail shops, when you buy an tire or when you buy a TV?
Tips were supposed to be something extra, an non-mandatory additional monetary reward for an outstanding service, but its purpose has turned more into a obligation nowadays and restaurant owners have been taking advantage of it to pay their staff less.
At work, I do my best and don't get tips, Should I?
The core issue here is that waiters/waitress/cooks/staff don't earn enough at restaurants because restaurant owners don't pay enough, and they make the diners accountable for it by asking to pay 15%/20% more on top of the bill.
In short: Choriarte's owners - Pay your staff more so they don't have the need for asking diners for more tips.
Needless to say I won't recommend this place as I used to do.
