When I travel, I've often worked the night before. Last week, worked 7p-7a in Tacoma then caught the 8:15 am Cascades train (very occ, I'll fly the AS shuttle, but it takes longer) back to PDX. I went to the Bistro car and ordered a glass of wine. The lady behind me audibly snorted and mumbled something along the lines of "a bit early isn't it?" Hey lady, this is my happy hour! But I didn't say anything, just took my wine and quiche and sat down to enjoy it.
