The best restaurants serving Spanish food in Castle Lincoln East Midlands

I am starting my review with the following statement that gets added to the bill so reviewers can see how this restaurant operates without having to read the full review ' 10% TIPS INCLUDED - FOR PARTIES OF 1 OR LARGER,  10% GRATUITITY IS APPLIED AUTOMATICALLY. IF YOU HAVE ANY QUESTIONS SPEAK TO THE MANAGER' We had 4 tapas and some bread and also ordered a bottle of wine. We asked for a bottle of Rioja that was listed on the menu but we were told that was not available, so we moved to the one above it instead. We waited for our wine but then we were informed by our waiter that instead he could offer us a different red and that it would be £40 (approx.)  I said well the wine I ordered was around the £30 mark and didn't really want to pay £40 - mainly because I am not sure why the customer should have to fork out an extra £10 because they cannot locate the wines they have listed on their menu. He informed me that he would knock the service charge off the bill. I thought this is strange because we are only a table of 2 people, why would there be a service charge? Thankfully one of his colleagues located the bottle of wine we had ordered and the issue was resolved. Our food arrived and we must say, it really was mediocre. The gambas were incredibly expensive for the size of the portion and the size of the prawns. When the bill came we could see that they had added a 10% service charge with the statement on the receipt ' 10% TIPS INCLUDED - FOR PARTIES OF 1 OR LARGER,  10% GRATUITY IS APPLIED AUTOMATICALLY. IF YOU HAVE ANY QUESTIONS SPEAK TO THE MANAGER' What a strange approach and way to manage tips - tips SHOULD be discretionary, not mandated. Tips should be left based on the service received and the dining experience. Secondly, stating that 'for tables of 1 or more' automatic tips are applied,  you cannot get tables of less than 1 so basically this restaurant is stating that all diners will have this automatic tip applied. Would  we have left 10% for the food and service received , no we wouldn't have done. Will we be back or recommend this restaurant? No we will not.
