You never can tell, I have had it checked before at check in, and sometimes no. Always depends on the individual checking you in, but the rules are the rules so don’t go over your allowance.
All immigration offices in country are closed tomorrow the 14th due to a public holiday, they will be open again on Tuesday the 15th. Of course border checkpoints and airport immigration will be open as normal.
It is totally up to the immigration office you are using, some will require it, some will not, you are always best to go and ask what your particular office will require from you.
