Ha'il Airport

As Salaamu Alaikum: For some reason trolleys are not available to the general public. The workers at the airport keep the trolleys and won't make them available to the general public unless you give them 10 Riyals. Trolleys aren't even available for the general public to take a trolley as needed. The Trolley Mafia will not even give you a trolley unless you give them 10 Riyals first. Now if someone needs a trolley and a worker this service should be available, however if a patron doesn't need a worker trolleys should be available also. The airport in Yanbu has trolleys available for departures and arrivals inside and outside the airport terminal. Perhaps management should look into this situation. I hope this could be resolved. Thank you very much.
