We were waiting outside the shop for some time but no one was attending to us, even though there are 2 empty tables presumably because it’s dinner time.

After waiting for some time and still nobody is attending to us, and there were empty tables, we walked in and took a seat at one of the tables.

Then a tall male staff came walking in and started screaming at us in front of all other customers asking if we had done safe entry (which we did and showed him). Yet he continue to be rude and scolded us for not waiting outside to be seated, and claimed that they were busy!
