Contacting ETASA/Transporte Terrestre

I absolutely adore malaprops. I will sometimes say, "Adios, Amoebas!" to my friends. Or if it is a group of women, I will say, "Adios, Machacas!" I have a business associate who speaks perfect Spanish. I play the dumb gringo whose Spanish is very dicey. When we are talking up potential clients, I will try to lighten the conservation by saying, "Somos sucios."
