This past Tuesday ORF/LGA (Republic E 175) I was the ONLY pax in F with just about six in Y. F FA refused to serve me a PDB claiming it was against health and safety regulations. Then she somewhat rudely served me one drink in air, no snacks, then ran in the back of the plane and crouched down in the last (empty) row of Y. The Y FA had to finally pick up my glass before landing.
Same day LGA/DCA A319 PDB as soon as I boarded with more offers as we sat through a 2 hour plus maintenance delay. Said problem took just 15 minutes to fix but we spend endless time waiting to be towed back to a gate then pushed off the gate once the maintenance issue was resolved. Of course, great service in air.
