Double standards

<p>We flew with Thai Lion Air on 27 December from Bangkok to Chiang Mai with no problems and then flying out of Chiang Mai on 1 January we flew out to Bangkok and was stopped with our powerbanks that according to airline rules now suddenly i am not allowed to take them and was made to feel that I did something wrong. I understand rules but not how once it is acceptable and then next time not, if I had known i would not have taken it first time. Unacceptable double standards that make you feel guilty because of their inappropriate actions.</p>
