No maintenance at TOTAL ant Orpen Gate

Just returned from visit to Kruger park. Last year we exited the park at Orpen gate. Tried to check my tires pressure, but the compressor didn't work. Now we exited again at Orpen gate and this time the compressor worked but the pressure gauge did not. No maintenance. Why are they wasting money in signs inside the park "Thank you for choosing TOTAL". There are no other petrol stations in the park.
