"the waiters were unflurried and good natured" "with contented mind and unruffled spirit"
(of a body of water) free from disturbance by heavy waves;
"a ribbon of sand between the angry sea and the placid bay" "the quiet waters of a lagoon" "a lake of tranquil blue water reflecting a tranquil blue sky" "a smooth channel crossing" "scarcely a ripple on the still water" "unruffled water"
