Samitivej Upselling services?

Does anyone feel that Samitivej upsells services? I started going to Bumrungrad few years ago and have found them excellent. Have gone to Samitivej a few times for minor ailments in between because of the lower charges, but always ended up paying as much or more because of how many tests they make you do.

Eg I once went for a sinus headache (I have chronic sinusitis) and asked them to prescribe me a a specific spray but they made me get a neuro consult and a head CT.

Am I being paranoid?

Edit : Thanks to everyone, I realise Samitivej is no better or no worse than Bumrungrad. I will give them another chance.
