Fabricio Estrada, the blogger from Bitácora del párvulo [es] summarizes the speech of a trader that uses a bus as sales venue:

Allow me, kind travelers, to interrumpt your nap or the conversation held with your companion or newspaper. I'm here just to offer you the so desired health, just discovered by the laboratory I work for, cheap, so you may get home happy and with a present for yourself and your family.
