Lucky HV level 7, they replace bed sheet every session
Last time only T50 and T21 have fabric seats
Anyway that time saw one lady on bus j13 (one of the old bus who get repainting), boarded at larkin. She put reusable bag as seat cover. Sat for one minute, saw her face still not comfortable, then stood up again. Then sat again for 1-2 mins, then decided to stand for whole journey. She didn't want to touch the seat cover again after that. Holding the pole also using tissue paper. Must be one of the germs freak.
