Wheelchair Procedures and/or Etiquette?
I was dining with friends last night and since they know that I travel a lot for business and pleasure, they mentioned that they were going to be traveling with an infirm relative who needed wheelchair services for a domestic, then an international trip... They asked if I knew whether wheelchair services at airports were free and if so, what's the standard tip, etc?
I don't know! How much should one tip a wheelchair attendant? What's the wheelchair procedure and/or etiquette at U.S. and foreign airports? If anyone with experience in this can shed some light, thanks in advance, I'd appreciate it.
