The shortest distance between two points and the longest distance between two drinks.
means Extending or moving in one unbroken direction without bends, curves, or interruption; by extension, honest, direct, or undiluted.
from From Middle English 'streght,' which is really the past participle of the verb 'strecchen' — to stretch. So a straight line is literally a 'stretched' line: pull anything taut and the slack vanishes, leaving the shortest path between its ends. The same logic let the word drift into meaning honest and undiluted — a 'straight' answer or a drink taken neat, with nothing bending it out of true.
