What was the reaction of the shopkeepers who denied oil to Sai Baba?

When the grocers refused to give Sai Baba oil, they watched to see what he would do, viewing his daily collection as a nuisance they wanted to stop. However, their amusement turned to astonishment. According to Chapter 5, after Baba miraculously lit the lamps with water, the grocers were so amazed they 'put their fingers in their mouths.' They realized they had sinned by lying and had given Baba needless trouble. The text states that as the water-fueled lamps burned all night, the grocers began to tremble everywhere with repentance for their actions.
