Sounds like a poor example of how it should be done, but sadly familiar, so often a discover scuba experience(DSD) is badly performed resulting in what should be future divers leaving to never try again. When we do a DSD it takes about 2 hours, starting with a briefing then shown how the equipment works, this is followed by a session in shallow water to get used to breathing and calm nerves, then if all parties are happy we then take you for a dive, anything less is bad practice. Do hope you give it another try some day, maybe when all this virus thing is done you could treat yourselves to a holiday in the Philippines and come learn with us. Stay safe dude
