He buys 2*5=<<2*5=10>>10 drinks for his friends
So he orders 10+6=<<10+6=16>>16 total drinks.
The cost of the drinks was 16*6=$<<16*6=96>>96
So his order came out to 96+14=$<<96+14=110>>110
The tip came out to 110*.3=$<<110*.3=33>>33
So his order cost 110+33=$<<110+33=143>>143
Adding in the cover charge means it cost 143+20=$<<143+20=163>>163
