DALLAS—Greyhound passengers accustomed to complimentary vomiting in the aisles will now be charged a $15 fee to do so, com≠pany representatives announced Monday. "In order to better serve our customers in the future, we have instituted a small surcharge for those needing to empty their stomach down the center walkway," said spokesman Don Randall, adding that once riders wipe themselves off, they can pay with any major debit or credit card. "We recommend passengers wishing to avoid paying the fee puke on one of the chairs in the terminal beforehand." Despite the new changes, Randall assured customers that masturbating under a bulky winter coat would always be free.
