In my restaurant, there are two blackboards on the terrace announcing that WE ONLY OPERATE AS A RESTAURANT. I don't offer cafeteria or bar service. It's spelled out in writing. If you think that's rude, I think it's even worse if you try to break the written and posted rules of my business, and I won't allow it. En mi restaurante hay dos pizarras en la terraza que anuncian que SOLO TRABAJAMOS COMO RESTAURANTE. No ofrezco servicio de cafetería ni de bar. Está explicado por escrito. Si te parece rudo, a mí me parece peor que tú quieras saltarte las reglas escritas y anunciadas de mi negocio y no lo voy a permitir.
