Prateep Chaikul of Si Ra Cha district has been selling fruit and vegetables from his motorcycle sidecar to raise extra money for the care of his wife, Suchada Phoklang, 48.
A sympathetic Facebook user posted his photo on Facebook and reported his plight, which prompted members of a motorcycle club to visit the couple on Wednesday evening and give them a generous donation.
Prateep said other people have called him and transferred money, and government agencies were also offering assistance.
He has additional specific requests. He needs an electric fan because their rented room gets hot, and his wife needs L-size adult diapers and medical materials to treat bedsores.
