If you're adding the air in a warm garage or on a warm day, add a couple extra PSI. When it gets colder out (or once your car is outside) the air becomes more dense and you will "lose" pressure.
Rule of thumb is 1psi extra for every 10°C
E.g. adding air in a warm 20°C garage --> -30°C outside = up to 5 PSI extra required.
Anyway, you should be following the target the pressure shown on the manufacturer stamp unless you have changed tire sizes. Bigger rims = more pressure required. In the winter people often go down rim sizes, so that would be one explanation for the lower pressure that the garage is giving you... however garages are also frequently wrong

I pumped all my summer tires to 45-50PSI because 1 was leaking air every 3days. Getting new set in summer

A Loonie felled from my hand and slipped inside the Gear box. Couldn't imagine such a thing could happen.
Any idea how we can open the cover in the gear shift knob and remove the coin ?
