Went to IHOP around 11:45 pm and as I walked in the server told me they were closed . I guess because the night server didn't show up ... The least she could have done was stay an extra 30 min to serve us and and satisfy us. Instead when I responded "I don't understand you guys are open 24 hours" she got frustrated and repeated that someone didn't show up in a negative tone. I've worked in the restaurant all my life and I know I would have stayed the extra 30 min and for me being the customer I would have tipped her graciously for going the extra mile and staying past her shift . This will be the last time I go to this I hop .
