I asked for face mask when boarding the airplane but to my dismay they did not stock COVID-19 face mask onboard and it would have been okay but the crew member said "you should have bought one" which totally is disrespectable and not appropriate as this totally goes against their policy of COVID-19 deterrence policy which they have laid out in their online app as well as their website. Although I made an online complaint regarding this matter....But so far nothing has been said or done! Very disappointed.
