Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Ex Input:
Every time you shop at airports the shop personnel ask to see your boarding pass even if there's no discount on the merchandise due to the lack of VAT. Given that the GDPR is now in force starting from 25.05.2018, can I refuse to show my boarding pass at EU airports, citing privacy concerns? Or can I at least demand an explanation from the shop keeper of how my personal data is stored?


Ex Output:
Does the GDPR entitle me to refuse to show my boarding pass at EU airport shops?


Ex Input:
I'm planning to visit a few places in Egypt during the month of January or February.  The locations on my itinerary are:


Cairo
Alexandria
Aswan
Abu Simbel
Luxor


I plan to spend anywhere from 1 to 2 days at those locations.  Is it culturally acceptable for a male to wear shorts, tshirts and flip flops?  What's the temperature like at this time of the year?  Will I need a sweater?  Are hiking boots required or just the general walking shoes?  My tour will not include hiking for more than 1 hour.


Ex Output:
What kind of clothes and footwear are ideal to visit Egypt?


Ex Input:
I'm 15 days into a 30-day trip all across Greece (Athens, northern mainland, islands). Everything has been great except the long wait each time we are ready to pay our bill when we're out to eat or for drinks. In America, cleared plates or a credit card/cash sitting on the table is an indication that we are ready to leave. Here it seems they are in no rush at all. We've even waited 20 minutes (they weren't busy). They print the tickets and bring them out immediately but take much longer to take payment. Multiple times we've had to walk to them - which feels a bit rude.

My question
How do I more clearly indicate that I am ready to pay and leave?
or
Am I just being an impatient American not attuned to the Mediterranean pace of life?
