"Infractible" is a word in ENGLISH

Two small time thieves had been sent by the Big Boss to steal a van load of goods from a bathroom suppliers. One stayed in the van as look out and the other went into the storeroom. Fifteen minutes went by, then half an hour, then an hour, and no sign of him. The look out finally grew impatient and went to look for his partner. Inside the store the two came face to face. "Where have you been?" demanded the worried look out. "The boss told me to take a bath, but I couldn't find the soap and a towel."
